The TI 36X Pro can solve these equations in num-solve if you use classic entry mode (max of 80 characters), and enter your function of interest into table app under choice 2. Then go to num-solve. Enter your equation in terms of f(x)...example: 0=d/dx(f(x)lx=x) by entering num-solve, make left side "0"(delete anything that was on left side), right side, press d/dx press table, press choice 1, complete the()'s, enter. This will take you to the solve environment. Enter a guess for x, solve, and it will produce the nearest max or min point for your f(x). If you want to know what f(x) is at that x value, press num-solve, delete "0", press variable key twice to cycle to "y", go to right hand term, put curser over the d of the d/dx, press delete. This will leave you with y=f(x). press enter to return to solve environment. Leave your "x" value alone, solve for y, and this gives your f(x) value for your max or min point!

Solving for a specified area under the curve can be done by entering into table, choice 2, say, fint(sin(x)*x^2,x,0,x), pressing num solve, entering , say, 2=f(x) again, f(x entered by pressing table, choice 1, completing()'s. Press enter, and enter a guess for x and solve.

In all cases, making a quick table for your function of interest will facilitate making a reasonable guess to enter into the solve environment.

Have fun!
