If cos+cos^2 =1 then find the value of sin^2+sin^4

The value of   is  1  

Step-by-step explanation:

Given as :

cos x + cos² x = 1

So, = sin²x + (sin²x)²

Or, = sin²x + (1 - cos²x)²    

AS given in question that  cos x + cos² x = 1

I.e cox = 1 - cos²x

So, = sin²x + cos²x  

∵ Note:  sin²x + cos²x = 1

∴ = 1

Hence the value of   is  1  Answer
