Cos theta formula can also be calculated from the product of the tangent of the angle with the sine of the angle cos sin tan The derivative of cos in calculus is sin and the integral of it is sin The reciprocal of cos theta is Answer c 6 67 How to Remember How can you remember the formula Well it helps to know it s the Pythagoras Theorem with something extra so it works for all triangles Pythagoras Theorem only for Right Angled Triangles a2 b2 c2 Law of Cosines for all triangles a2 b2 2ab cos C c2 So to remember it
The fundamental cos theta formula that you use for calculating the cosine is cos base hypotenuse Here The base is known to be the base of the triangle while the hypotenuse is the side opposite to the right angle of the triangle Angle Hypotenuse Adjacent Opposite Sine Cosine and Tangent The three main functions in trigonometry are Sine Cosine and Tangent They are just the length of one side divided by another For a right triangle with an angle Sine Function sin Opposite Hypotenuse Cosine Function cos Adjacent Hypotenuse
