It looks like you're missing some parentheses.
I think this is the equation you mean:
sin(x)/(1-cos(x)) + sin(x)/(1+cos(x))
your common denominator is (1-cos(x))*(1+cos(x)), which is the difference of squares simplification and is equal to (1-cos^2(x)) = sin^2(x)
Numerator: sin(x)*(1+cos(x)) + sin(x)*(1-cos(x))
= sin(x) +sin(x)cos(x) + sin(x) - sin(x)cos(x)
= 2sin(x)
Answer: 2sin(x)/sin^2(x) = 2/sin(x) = 2csc(x)
Answer:
A) y=1/3x+5
B) y=-2x+9
C) y=-3
D) y=2x+9
E) y=-10x+80
F) y=x-2
Explanation:
Use y=mx+b
m=slope
b=starting point (or where it crosses the y-axis
For slope, use rise over run.
To determine negative slope, read from left to right and see if it’s going up or down. If down it’s negative, if up then positive.
Also BE CAREFUL, on D, the y-axis is labeled differently. Take an extra look at it.
Factor out the 5. 5(x - 6)
