This is a quick reminder on how to use mathematical functions inside JavaScript.
Instructions
- Use
*to indicate multiplication: Type4*xfor 4x; - Use
^to indicate powers: Type4*x^3for 4×3 and12*x^-6for 12x?6. - Use parentheses to delimit the argument of a function; i.e., type
sin(x)rather thansin x. - Use parentheses to define the scope of an operation: For example, type
4*x*(x^2+1)^3for 4x(x2+1)3 or4^(2*x+1)for 42x+1 or(sin(x))^2for (sin(x))2. - Do not type sin^2(x) for sin2(x), type
(sin(x))^2instead. - Do not use brackets [ ] or braces { }, use only parentheses to delimit a mathematics expression.
- Functions you may use:
Trig: sin, cos, tan, cot, sec, csc;
Inverse Trig: asin, acos, atan;
Log/exponential: ln (natural log), or use log; exp, the natural exponential; Note: You can also enter the natural exponential exp(x) as e^x for ex.
Misc: sqrt, usage sqrt(x) for ?x (or, use exponential notation: x^(1/2)).
