Answer:
Step-by-step explanation:
To do this, we must use the unit circle. At the angle
the coordinate pair is (
,
) and the hypotenuse is 1
Now that we know these we can start using the trig functions
sin = y
cos = x
tan = 
And the other functions would be the reciprocal of these
csc = 
sec = 
cot = 
This would mean that
sinx = 
cosx =
tanx =
or
if you're supposed to rationalize your denominators
cscx = 2
secx =
or 
cot = 
Answer:
9 and 18

Step-by-step explanation:
, the answer 17.25, there must a be a typo in your question
Answer:
-21/32
Step-by-step explanation:
It's easier to do this multiplication mentally if we rewrite the expression as follows:
-3 7 -21
------ * ------ = ---------
4 8 32
Solution:
The given equation is

Now we will factor the middle term as per the ac-method because the given equation is a quadratic equation.
