Question

If x = b sin theta and y = b cos theta, then find the value of x²+y².
​

Answer 1

Answer:

Answer is b²

Step-by-step explanation:

x + y

then squaring this equation

x²+y²

(b sinthetha)² + (b costhetha)²

b² ( sin²thetha + cos²thetha)

b²(1).

{ As- sin²thetha + cos²thetha=1}

Hence answer is b²
