random Flashcards
1
Q
differentiate a^(x)
A
a^(x)ln(a)
2
Q
why might the Newton-Raphson method fail?
A
if f’(x)=0 then the tangent is vertical and values won’t converge (to meet a root)
3
Q
how to integrate parametric equations
A
int[(y)(dx/dt)]dt
FIND NEW LIMITS (sub in x values to find t limits)
4
Q
differentiate parametric equations
A
dy/dx = (dy/dt)(dt/dx)
