Question
Evaluate the following. sin 25° sin 65° – cos
25° cos 65°.Solution
sin 25° sin 65° – cos 25° cos 65° We know that the formula is cos (A + B) = cos A cos B - sin A sin B -cos (A + B) = sin A sin B - cos A cos B so, sin 25° sin 65° - cos 25°cos 65° can be written as => -cos(25° + 65°) = -cos (90°) = 0
