Hyy Dude ♡

The value of sin ² a + sin ⁴ a is 1

Step-by-step explanation :

• ➨Cos a + cos ² a = 1

We have to find the value of

• ➨Sin ²a + sin ⁴ a

As,

• ➨Sin ²a + cos ² a = 1

Given,

• ➨Cos a = 1 - cos ²a = sin ² a

• ➨Sin ² a + sin ⁴ a

Put the value of sin ²a

• ➨cos a + cos ² a

• ➨1

Hope it's helps you ♡
