Question

If tan tetha = a/b
then value of
asin tetha - bcos tetha / asin tetha + b cos tetha ​

Answer 1

Answer:

asquare-bsquare÷asquare+bsquare

Step-by-step explanation:

1) asin tetha-bcos tetha÷asin tetha+bcos tetha.

2) sin tetha= a÷root a square + b square, cos thetha= b÷root a square + b square.

3) If we substitute the step 2 values in step 1 equation. Then,We get the answer a square- b square ÷ a square + b square.
