In my math class, we are not allowed to use calculators. Thus, when I see problems with an exponent/log or trig either in top or bottom and I have to graph them to solve the problem, I'm not sure where to start. Could someone give pointers as to how I should approach this?
For example: (functions that follow this type of format)
- (e^x / sinx)
- (e^x / 6x)
- (sinx * e^x / cosx)
- sqrt(1-e^x)
Similarly, why does sqrt(1+x^2) look similar to the absolute value function when the sqrt function and parabola is combined? Should I be looking at domain/range of outer to inner?
