Hello everyone. I officially have the worst Trig teacher in America and I have never been so confused in a math class before. I have at least 5 problems (only 2 posted here) I'm struggling with and need to figure out before my exam tomorrow. Any help is much appreciated.
1.
The function f(x) = x - sin x is odd. True or False?
From my professors review I know it's True but his explanation was so unclear I don't know why. ??2.
sin[tex]\alpha[/tex][tex]/[/tex]1-cos[tex]\alpha[/tex]- sin[tex]\alpha[/tex][tex]/[/tex]1+cos[tex]\alpha[/tex]=
I ended up with 0 as the solution. ??
