Simplify: (sin θ − cos θ)2 − (sin θ + cos θ)2

a. -4sin(θ)cos(θ)
b. 2
c. sin^2θ
d. cos^2θ

The  Solution is below. That is the option a. -4sin (θ)cos (θ)

Step-by-step explanation:

Simplify: (sin θ − cos θ)2 − (sin θ + cos θ)2

Solution:

We know the Identity

Applying this Identity we get

Now Plus sin θ Minus sin θ and Plus cos θ Minus cos θ will cancel each other then we have,

The  Solution is the option a. -4sin (θ)cos (θ)

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6

answer: add the !

step-by-step explanation: then we will answer
