Question

if x=a sin thita and y =a cos thita then the value of x^2+y^2 is​

Answer 1

Answer:

1

Step-by-step explanation:

(sin tita)^2+(cos tita)^2=1

Answer 2

Answer:

a^2

Step-by-step explanation:

x^2+ y^2

=a^2 sin^2 theta +a^2 cos^2 theta

=a^2(sin^2 theta+cos^2 theta)

=a^2 ( sin^2 theta+ cos^2theta=1)
