The first simplify expression was posted weirdly
it is supposed to read
1 + cosx divided by sinx + sin x divided by 1 + cosx
I have a collection of Trig problems that are giving me some difficulty...
1. Finding the Period, Phase Shift, and Asymptotes for the following expressions
3+4cot(5x-2)
y=-3tan2(pi X-pi/4)
2. Find the exact value for
tan105
sin195
cos51cos9-sin51sin9
3.Simplify the expression
1+cosx + sin x
sin x 1+cos x
1+secx
sinx + tanx
1 +siny
1 +cscy
thanks in advance for all help...these are some HW problems that i am confused on and i have an exam in the coming week, so if explanations could be given for all problems that would be nice as well
Hello again, mmgolf!
For #2, you need some Sum/Difference formulas.
2. Find the exact value for:
We note that: .
. . and we use: .
Hence we have: .
Can you finish it now?
Note that: .
. ,and we use: .
So we have: . . . . etc.
You're expected to recognize that this is the right side of the formula:
. .
Got it?
