In quadrant IV, cosine is positive and sine is negative. This means that
The cotangent is defined as the ratio between the cosine and sine:
So, we have the following equation:
Squaring both sides yields
The solution to this equation would be
But we know that the cosine has to be positive, so we have
And
Finally, the secant is the inverse of the cosine, so it's
Answer:
13
Step-by-step explanation:
Which one are you talking about
This is an exponential function.
Without any transformations (up or down), the range is y > 0
Answer:
angle 7 is 112
Step-by-step explanation:
angles 2 and 6 are congruent, and vertical angles are also congruent, so you know that angles 2 and 7 have the same value
