Scientific Calculator Created Using Visual BasicThis is a calculator that resembles a typical scientific calculator , albeit a simpler version. In our version, we have only included the trigonometric functions and the logarithmic functions. The reason of creating a simpler version of the calculator is to help users to learn the programming concepts in a gradual manner and not to confuse them especially those who are learning to program in Visual Basic.To design the interface, we just to need to modify the interface of the basic calculator that we have created earlier using Visual Basic 6. In this calculator, we have added five more buttons, they are Sin, Cos, Tan, Log and Ln. The common trigonometric functions in Visual Basic 6 are Sin, Cos, Tan and Atn.a) Sin is the function that computes the value of sine of an angle in radian.b) Cos is the function that computes the value of cosine of an angle in radian.c) Tan is the function that computes the value of tangent of an angle in radian.d) Atn is the function that computes the value of arc tangent of an angle in radian.Log computes the value of logarithm to base 10 whilst Ln computes the value of natural logarithm.An angle in degree has to be converted to radian before it can be calculated by the above trigonometric functions. From high school mathematics, we know that π radian is equivalent to 180°; which means 1 radian is equivalent to π divided by 180. Therefore, in orderCalculator sin cos tan - YouTube

This tool helps you calculate trigonometric values like sine, cosine, and tangent for any given angle.How to Use the Trigonometry CalculatorTo use this trigonometry calculator, simply enter an angle in degrees into the input field and click the “Calculate” button. The calculator will then display the sine, cosine, tangent, secant, cosecant, and cotangent values for the given angle. The values are rounded to six decimal places for precision.Explanation of CalculationsThis calculator performs the following trigonometric calculations:Sine (sin): sin(angle) = opposite/hypotenuseCosine (cos): cos(angle) = adjacent/hypotenuseTangent (tan): tan(angle) = opposite/adjacentSecant (sec): sec(angle) = 1/cos(angle)Cosecant (cosec): cosec(angle) = 1/sin(angle)Cotangent (cot): cot(angle) = 1/tan(angle)LimitationsPlease note that secant, cosecant, and cotangent values are marked as “undefined” for angles where they do not have valid values (e.g., sec(90°), cosec(0°), cot(0°)). This is because there are points where the cosine, sine, and tangent functions respectively have values of zero, which would cause a division by zero error. Always ensure the input is a valid number.Use Cases for This CalculatorCalculate Angles in Triangle ProblemsWhen faced with a triangle problem, you often need to find missing angles. By inputting the lengths of the sides, you can use the trigonometry calculator to easily derive the angles using the sine, cosine, or tangent functions, streamlining your problem-solving process.This not only saves time but also ensures accuracy in your calculations, allowing you to focus on higher-level concepts instead of getting bogged down in manual math.Determine Heights and DistancesIn fields like architecture or physics, you frequently need to measure heights and distances that are difficult to obtain directly. By leveraging the sine or cosine of an angle, you can input the known values into the calculator to find these measurements efficiently.This practical application turns complex real-world scenarios into manageable calculations, enhancing your ability to derive meaningful insights from your data.Analyze Waves and OscillationsIfTrigonometry Calculator - Calculate Sin, Cos, Tan and More

Trigonometric Calculator - Quickly calculate sin, cos, tan
With this calculator you can calculate the area, the perimeter, the altitudes and the lengths of the diagonals of a parallelogram. The calculation path is always given as well. It can be selected to how many decimal places the calculated values should be rounded and further calculations are always performed with the rounded values.To calculate all values of a parallelogram at least 3 input values are needed. Often, however, one does not want to calculate all values, but only a certain one and for this 2 input values are often sufficient. For example, the area can be calculated from a side length and the corresponding altitude. Therefore, it is also possible with this calculator to select that only 2 input values should be specified..ContentsFormulasWhat is a parallelogram?Interior anglesAltitudesAreaPerimeterDiagonal lengthsParallelogram lawFormulasAnglesα + β = 180°Altitudesha = b ∙ sin(α)hb = a ∙ sin(β)AreaA = a ∙ haA = b ∙ hbPerimeterP = 2 ∙ (a + b)Diagonal lengthse = a² + b² − 2 ∙ a ∙ b ∙ cos(β)e = a² + b² + 2 ∙ a ∙ b ∙ cos(α)f = a² + b² − 2 ∙ a ∙ b ∙ cos(α)f = a² + b² + 2 ∙ a ∙ b ∙ cos(β)Parallelogram lawe² + f² = 2 ∙ (a² + b²)What is a parallelogram?A parallelogram is a quadrilateral in which opposite sides are parallel. Due to the parallelism of the opposite sides, opposite sides also have the same length and opposite angles are equal.In the figure above, the sides with side lengths a and c are equal in length and parallel to each other, and the sides with side lengths b and d are equal in length and parallel to each other. Furthermore, the angles α and γ are equal and the angles β and δ are equal.Interior anglesThe sum of the interior angles of a quadrilateral is always 360°. Since α = γ and β = δ holds, the sum of α and β must be 180°.α+β=180°AltitudesIf you draw an altitude ha from the side with the length a in such a way that one end of the altitude lies in point C (and if necessary you also draw an extension of the line AB), then a right-angled triangle is formed. Line CB is the hypotenuse of this triangle and has length b. The angle in the right triangle at point A is either α or β. The opposite of this angle is the altitude ha.For the acute angles in a right triangle holds:Depending on whether the angle at B in the right triangle is α or β, either sin(α) = or sin(β) = applies.For angles between 0° and 180°, sin(angle) = sin(180° − angle) applies. In a parallelogram, the sum of α and β is 180°. Thus β = 180° − α applies. From this follows sin(β) = sin(180° − α) = sin(α). Thus, regardless of whether the angle in the right triangle at the corner B is α or β, the following applies:If youSin Cos Tan Scientific Calculator - Now Calculator
