Answer:
(- 1/2 , √3/2)
Step-by-step explanation:
t=20π/3
t' = 20π/3 - 6π = 2π/3 (120°) ... 2nd quadrant
If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)
OF/OE = - cos 60° = x / 1 = - 1/2
FE/OE = sin 60° = y/1 = √3/2
Answer:
A= 16
B=?
Step-by-step explanation: srry about the second one im also confused but i tried my best.
Answer:
0
Step-by-step explanation:
Hello, dividing by 0 is not defined. so

is defined for x different from 0
This being said, we can simplify by 2x

and this last expression is defined for any real number x.
Thank you
Answer: 37 you just add the two in that case
Answer:
Given:
f(x) = 4x² + 1
g(x) = x² - 5
Then
(f + g)(x) = 4x² + 1 + x² - 5
= 5x² - 4
Answer: 5x² - 4
