Alg 2

Answer 1

Answer 2

In the unit circle, all ordered pairs (x,y) satisfy the relation \(x^2+y^2=1\).
Using this, you would be able to find y using \((-3/5)^2+y^2=1\).
But note that since it is given that the angle is in the third quadrant, so both x, y would be negative.
Once you have y, \(\sec \theta =1/x\), and \(\cot \theta = x/y \).
Here's a chart for the quadrants that might help your other questions:

Could you walk me throught step by step bc I didn't understand any of that

Answer 5

"In the unit circle, all ordered pairs (x,y) satisfy the relation x2+y2=1.
Using this, you would be able to find y using (−3/5)2+y2=1."
Can you do this step of solving for y?

Answer 6

y = 11/5

Answer 7

Sorry, my bad. Copy and paste does not work automatically. Sigh...
The equation should read:
\((−3/5)^2+y^2=1\)

Answer 8

How do I multiply fractions

Answer 9

Fractions are multiplied : numerator \(\times\) numerator, and denominator \(\times\) denominator.
For example:
\(\Large\frac{4}{3}\times\frac{5}{7}=\frac{4\times 5}{3\times 7}=\frac{20}{21}\)
