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

step-by-step explanation:

basically 2/5.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
