Square both sides of the equation a2 = (x - c)2 + y2 Now, we need to find x and y and replace them in a2 = (x - c)2 + y2 Using the triangle, write expressions for sin A and cos A and then solve for x and y.
Cosine rule, in trigonometry, is used to find the sides and angles of a triangle. Cosine rule is also called law of cosine. This law says c^2 = a^2 + b^2 − 2ab cos(C). Learn to prove the rule with examples at BYJU’S.

What is the formula of (1 - cos x) / sin x - The formula of (1 - cos x) / sin x = tan (x/2)
It is also possible to use cos2x = 1 -2sin^(2) x or cos 2x = 2cos^(2) x - 1. What is the double angle formula of tangent function? The double angle formula is used to calculate sin 2y, cos 2y, tan 2y, for any given angle 'y'. The tangent double angle formula states ...
