calculus question......
the position function s of a point is given by two dimensional quantities where t in seconds and the y direction is affected by gravity (10m/s/s). y(t)=4t*sin(θ) - 5t2 & x(t)=4t*cos(θ) 1-...

How do you find the equation to an integral when the equation is not given but the answer to the integral is?
int; integral sign Find int (bottom: -3 top: -5.5) (8*f(x)-9)dx when int (bottom:-5.5 top:-3) f(x)dx = -2 Also; let int (bottom: -8 top: -0.5) f(x)dx =8 int (bottom: -8 top: -5.5)...
