You have the following expression:
To verify the identity, you have that the left side of the equation becomes:
(1 + cosx)(1 - cosx) = (1 - cos^2 x)
because of the product of an expression by its conjugate result in a difference of squares. Or simplfy by expanding the factors and simplying.
Next, you have:
1 - cos^2 x = sin^2 x
because the Pythagorean identity.
Then, the identity is verified.
Answer:
The answer is t>0
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2<3t−2
Step 1: Flip the equation.
3t−2>−2
Step 2: Add 2 to both sides.
3t−2+2>−2+2
3t>0
Step 3: Divide both sides by 3.
3t
/3 > 0/3
<em><u>t>0
</u></em>
