Answer:
Yes
Step-by-step explanation:
Because 35 * 1 is 35 and 35 * 2 is 70
Answer:
Step-by-step explanation:
The point slope form of a line is 
where 
. We write
Convert point slope form to slope intercept form by simplifying and rearranging.
Cos(2x) = cos^2(x) - sin^2(x) - cos(x)
but sin^2(x) = 1 - cos^2(x)
cos(2x) - cos(x) = cos^2(x) - (1 - cos^2(x) ) - cos(x)
cos(2x) - cos(x) = cos^2(x) - 1 + cos^2(x) - cos(x)
cos(2x) - cos(x) = 2cos^2(x) - 1 - cos(x)
cos(2x) - cos(x) = (2cos(x) + 1)(cos(x) - 1)
I think this is what you have asked for.
