This week in advanced math we review Chapter Seven. We also had two test this week which made us put what we learned to the test. We really had to study and know the Trig Chart, as well as all of the formulas we have learned. On Monday through Wednesday evening we had to do a blog on SIN, COS, TAN, COT, SEC, and CSC. Then on Friday we went on to the next section, section 8-1. 8-1 has to do with finding the angles within quadrants. Here are the steps to finding the quadrant angle.

1) First you must solve for theta, to do this you get the trig function by itself and then take an inverse.

2) Then you find if the angle is based on trig function and if the number is tve or -ve.

3)
a)Take the inverse of the tve number to find the quadrant 1 angle.
b)Make -ve and add 180 to find quadrant 2 angle.
c) Add 180 to find quadrant 3 angle.
d)Make -ve add 360 for quadrant 4 angle.

Example: 2Cos(theta) +7=5

1) Subtract 7 from 5 to get 2Cos(theta)= -2

2) Divide -2 by 2 to get Cos(theta)= -1

3)Move cos to the other side to get theta= cos^-1 (1)

4) Cos is negative in quadrants 2 and 3 and cos6-1 (1) = 0.

5)so in quadrant 2 theta=180 and in quadrant 3 theta=180.
