PLEASE HELP ME FAST! THIS IS A SIMPLE TRIG PROBLEM BUT I SKIPPED CLASS.

Mathematics
1 answer:
NikAS [45]3 years ago
3 0

we can factor the whole thing:

(2sin(x) -1)(sin(x)+1) = 0.

Therefore, sin(x) = -1 and sin(x) = 1/2.

For the first one x = 3π/2 and the second is π/6 and 5π/6

So 3π/2, π/6 and 5π/6 are the solutions.

I do kind of have a problem with this because it doesn't mention if you should go over 360°. Otherwise, you have to add in an 2nπ into the equations like 3π/2 + 2nπ; n \in \mathbb{W}

but I don't know if that is necessary for you.

What are the eight related addition and subtraction equations for 48, 42, 6
Len [333]

Answer:

Many of these are just the same equation in different orders.

42 + 6 = 48

6 + 42 = 48

48 = 6 + 42

48 = 42 + 6

42 = 48 - 6

48 - 6 = 42

6 = 48 - 42

48 - 42 = 6
