Calculus Calculators
1.
Trigonometry
1.
Simplifying trigonometric equations, proving identities
, eg. (1) `sin(30)*cos(60)+sin(30)*cos(60)`, (2) `tan(x)+cot(x)`, (3) `tan^2(x)-sin^2(x)`, (4) `csc(x)/cos(x)-cos(x)/sin(x)`
2.1
If `sin(x)=5/13` then Find the value of all the other five trigonometric functions
2.2
If `sin(x)=3/5` then solve expression `cos(x)csc(x)+tan(x)sec(x)`
2.
Derivative
1.
Find Derivative
, eg. (1) `d/(dx)(2x^(3)-2x^(2)-5x+4)`, (2) `d/(dx)(log(x)e^(x))`, (3) `d/(dx)(3cos(sin(x)))`
2.
Find maximum and minimum value of `y=x^3+6x^2-15x+7`
