Basic Maple Commands with(plots): plot(expr.x): Plots expr over the default interval -10 x^2+5: Defines the function f(t) = 12 +5. Caution: The command subs(x=a, expr); only substitutes I = a into the evalf(expr): Evaluates expr as a floating point number. expression expr and does not change any previously assigned value of 1. expand(x^2*(2*x+1)^3): Distributes multiplication over addition. Limit(expr.x=a); Displays (but does not evaluate) lim expr. expand (sin(x+y)); Uses the formula for the sine of the sum of two angles to get sin (1) cos(y) + sin(y) cos(x). value(%): Computes the value of the previous output. expand (exp(2*x)): Expands er to the product ee. limit(expr.x=a): Evaluates the limit of expr as 1. simplify(expr): Algebraically simplifies expr. limit(expr.x= infinity); Evaluates the limit of expr as 1 + 0. factor(expr): Factors a polynomial expr. diff(expr.): Differentiates the expression expr with respect to I. The r is required although there may be no other variables in expr. solve(equation,x); Tries to give an exact solution listing all a's which solve an D(): Returns the derivative of the function f as a function. equation. If the equation is a polynomial of degree three or more, the solution may be expressed as RootsOf. Maple may not know how to find exact solutions Int(expr.x.x=a..b); Displays (but does not evaluate) Sexpr dr. in some cases. value(%): Computes the value of the previous output. % Refers to the output of the previous command. int(expr.x): Computes the indefinite integral of the expression expr with sol:=solve({eqn1,eqn2},{x,y}); Gives exact solutions I and y to the system respect to r. The answer is another expression. Note that the x is required, of simultaneous equations labeled eqnl and eqn2. If there is more than one even though there may be no other variables in expr. solution, they are sol[1] and sol(2). int(expr.x=a..b): Computes the definite integral of expr with respect to I assign(sol); Assigns the values found for I and y above to those variables. over the interval a
