I need a calculus review...my mid-term exam is in 1.5 hours...HELP?!? please?
I need formula's and review on: points of discontinuity, domain and range, limits, horizontal asymptotes, continuous functions, period and amplitute, finding half-life, slope between points, derivatives, equatiions of line to cuves (tangent lines) and position, velocity and accelleration
also, theres something i've never seen before...
e.g. cscx=2.3 on [0,2π] (π is pi) what is this and how do i solve it?

cscx = 2.3 on (0, 2pi)
To solve for x:
I hope you want to solve cosecx = 2.3.
But cosecx =1/sinx =2.3. Therefore,
sinx = 1/2.3
So x= arcsin(1/2.3) = 25.77146172 degree aaaapproximately.
Also x=25.7715+180 = 205.77146172 degree.
Or, x = 0.44979686 radians or x = 3.591389514 radians.
For other things, you study well and raise your doubt if you find any difficulty. There are expert editors through who will be glad to help you.
