Answer:

-1

Step-by-step explanation:

Evaluate for x=0

sin((2)(0))+sin(0)+cos((2)(0))−1(sin(0))(sin(0))−1(sin(0))−2

sin((2)(0))+sin(0)+cos((2)(0))−1(sin(0))(sin(0))−1(sin(0))−2

= −1

Answer:

sinx

Step-by-step explanation:

sin^2 + cos^2 = 1 (pythagorean identity)

therefore we take the square sin and cos out to make a 1

sin2x + sinx + cos2x - 1 sinx sinx - 1 sinx - 2

left with sinx -1 +1 =

sinx because the 1s cancel out
