Question

If tan x=b/a then find the value of (a^2+b^2)sin2x

Answer 1

tan x = b/a

so b is height and a is base

so Hypotenuse by pythagoras will be

=a² + b²

Sin2x = 2 sinx cosx

= 2 × height / Hypotenuse × base × Hypotenuse

= 2 × a × b / (root(a²+b²))²

so putting in (a² + b²) Sin2x

(a²+b²) × 2 × a ×b / (a² + b²)
