Ex 3.3, 6 - Prove that cos (pi/4 - x) cos (pi/4 - y) - Chapter 3
Ex 3.3, 6Prove that: cos (π/4−𝑥) cos (π/4−𝑦) – sin (π/4−𝑥) sin (π/4−𝑦) = sin⁡(𝑥 𝑦)Solving L.H.SWe know that cos (A B) = cos A cos B – sin A sin B The equation given in Question is of this form Where A = (𝜋/4 −𝑥) B = (𝜋/4 −𝑦) Hence cos (π/4−𝑥) cos (π/4−𝑦) – sin (
