Question

Cos^2a + cos^b = 2 , then the value of tan^3a + sin^5b will be

Answer 1

Answer:

1

IS THE ANSWER

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

Maximum value of Cos is 1. So  maximum value of cos square is also 1.

So, we can say,

Cos a = 1;  Cos b = 1

As 1 + 1 = 2

Means angle a is 0 degree and Angle b is also 0 degree.

So,

tan ^3a is 0.

Sin^3b is 0.

So answer is 0.

Hope it is clear.
