Answer :

The value of sin² a + sin⁴ a is 1

Step-by-step explanation :

Given,

• cos a + cos ² a = 1

We have to find the value of

• Sin² a + sin ⁴ a

As,

• Sin²a + cos ² a = 1

Given,

• ➨Cos a + cos ² a = 1

• cos a = 1 - cos ²a = sin ² a

• Sin ² a + sin ⁴ a

Put the value of sin²a

• cos a + cos ² a

• ➜ 1
