If (acosθ + bsinθ=p, \ asinθ - bcosθ=q,) then | Mathematics | SolveeIt

If $acosθ + bsinθ=p, \ asinθ - bcosθ=q,$ then

$a^2 + b^2 = p^2 + q^2$

$a^2 + b^2 = p^2 - q^2$

$a^2 - b^2 = p^2 + q^2$

$a^2 - b^2 = p^2 - q^2$

Answer

$a^2 + b^2 = p^2 + q^2$

Explanation

The correct option is (A): $a^2 + b^2 = p^2 + q^2$ .
