Quiz Cumulative Review Trig 1.1 and 1.3

The trigonometric functions 

 $\cos\theta\ \ and\ \sec\theta$  which are cousins, are both positive in which Quadrant?

• QI

• QIV

• QIII

• QII

We can use SOH-CAH-TOA for...

select the correct answer!

• Any triangle ever

• Non-right triangles only

• Right Triangles only

• Never

The trigonometric functions use the letters (x, y and r) to form their identities and create their values! Which of these letters will always have a positive value? Is it x,y or r? Only type one letter in lower case form.

What is the value of r, given the point

(-2, 10)? Make sure to pick the most simplified answer.

• $\sqrt{104}$

• $4\sqrt{6}$

• $2\sqrt{26}$

• $\sqrt{96}$

What are the trigonometric function values for

 $\sin\theta\ and\ \cos\theta$  if the given point is (3, -6)?
Select the correct answers.

•  $Sin\theta=-\frac{2\sqrt{5}}{5}$  

•  $Sin\theta=-\frac{2}{\sqrt{5}}$  

•  $Cos\theta=\frac{\sqrt{5}}{5}$  

•  $Cos\theta=\frac{1}{\sqrt{5}}$  

Given the picture Find the r value. Then find the  $Tan\theta,\ Cot\theta\ function\ values.$  

Select the correct answer.

•  $r=2\sqrt{5},Tan\theta=-2,Cot\theta=-\frac{1}{2}$  

•  $r=4\sqrt{5\ },\ \tan\theta=-\frac{1}{2},\ \cot\theta=-2$  

•  $r=\sqrt{20},Tan\theta=\frac{1}{2},Cot\theta=2$  

•  $r=2\sqrt{5},\ Tan\theta=-\frac{1}{2},Cot\theta=-2$
