We have sec =
1/cos
Then we also have
cos^2 = 1 – sin^2
Also we have cos = sqrt (1 – sin^2)
Substitute the derived cosine function to sec then we
have
Sec = 1/(sqrt(1-sin^2)
Answer:
Quadratic polynomial is x^2 - x - 20
Yes, three is greater than -2
Answer:
1/2
Step-by-step explanation:
The formula for slope is (y2 - y1)/(x2-x1)
In this case, it is (2 - 1/2)/(4-1) which is 1.5 over 3. The slope is 1/2
