Answer sin(theta/2)=1/2 i. write an equation that expresses the value of (theta/2) in terms of an appropriate inverse trigonometric expression. ii. on the interval [0, 2pi], what values of (theta/2) satisfy your equation in part i? iii. on the interval [0, 2pi], what values of theta does your answer to part ii produce? iv. write an expression for all solutions to the equation.

We'll use the notation for the principal value and for all the values:

Part I

Part II. In our range we can write

Part III.

Part IV.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
