Answer 2

ANSWER :- (b) r²

$\bf\huge\underline{\underline{ Given :- }}$

• x = r sin Q

• y = r cos Q

$\bf\huge\underline{\underline{ To \: Find:- }}$

• x² =( r sin Q)²

• = r² sin² Q

$\rule{10cm}{0.05cm}$

• y² = (r cos Q)²

• = r²cos²Q

$\rule{10cm}{0.05cm}$

• x² + y² = r²sin²Q + r²cos²Q

• = r²(sin²Q + cos²Q)

• = r²
