The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it ...

Math and conversions aren't everyone's strong suit, and that's all right. With this iOS 18 trick, you don't have to open your ...

Calculate the length AB. Give the answer to one decimal place. Label the sides of the triangle \(o\), \(a\) and \(h\). Next choose the correct ratio from \(s^o_h~c^a_h~t^o_a\). The length \(h\) is ...

The tangent line to a graph does not exist at a corner ... The Derivative of Sine 3.3 So you know the derivative of sine is cosine, but do you know why? This applet gives some pretty compelling visual ...

The app can also solve equations that use more complex formulas, like the trigonometric functions of sine, cosine and tangent. You need to include the equals sign (=) at the end no matter what.
