First Day Back from Spring Break

Hey guys! Hope you had a restful spring break and hard to believe we are 2 months away until June. To me feels like spring is finally here and I heard the Red River is going to rise, but before then ....Let's go over with some MATH!

Refresher

We are given some equations that look like Quadratic but also Trigonometric, but let's start with something easy. Like a refresher.

You with me so far? We'll have to factor out X and we will get

Then we equal the X as zero and for x-1 we put it to the other side and we'll have

Hope you haven't any trouble with these, Now let's move on to the real thing

Trigonometric equations

In this one we have Trig function like Tan in this example. Remember to follow the steps like quadratic equations. In this one we'll factor Tan x.

Feels like the last question.. Because it actually the same (To me at least)

This time now we have to inverse the Tan to find the value of X and we find the angles.

Now do the Cast Rule to find the angles you'll have answers like

So yup, hope this helps and also right because I'm actually unsure in the last part. ;) Don't hurt me the next day. :C

Good luck for the rest of the year!!11!
