#### x^2-3y=-32

y=4-3x

x^2-3y=-32

x=-4

x=-5

y=4-3(-4)

y=4-3(-5)

y=16

y=19

(x1,y1)=(-4,16)

(x2,y2)=(-5,19)

CHECK:

3(-4)+16=4

(-4)^2=3(16)=-32

4=4

-32=-32

3(-5)+19=4

(-5)^2-3(19)=-32

4=4

-32=-32

1-cos^2(x)=sin(x)tan(x)cos(x)
=cos(x)sin(x)/cosx x sin(x)

Cos(x)cos(x)sin(x)/cos(x)
=sin(x)sin(x)
=sin^2(x)
=1-sin^2(x)

Hello all,

I am currently majoring in Rad Tech, I became interested in my major through the love I have for science and helping people. This is my last math class (thank goodness.) its a requirement for my major before entering the Rad Tech program. After I graduate City Tech I plan to hopefully get a job at a great hospital and travel the world! From this course I hope to actually survive it then break up with math forever. (not a fan) Some of my many interests are music and fashion. Some of my hobbies are sewing, hunting for vintage clothing and eating. My favorite animal is the Jelly Fish.
