calculus again?
this one is smaller
Find f'(a).
f(t)=t^4 – 5t
Could someone explain to me about this problem then start it off…don’t do the whole problem just help…like a tutor would do
Thank You

Find f ‘ (a).
f(t)=t^4 – 5t
do you mean find f ‘ (t) ?
theres no “a” in the equation
this is the formula for the shortcut to a derivative (b is a constant and n is the exponent)
f (x) = t^n- bt^n
f ‘ (x) = nt^(n-1) bnt^(n-1)….. and so on depending on how many variables you have
i dont start it off because then you would have the answer

I do not know what method you are currently working on but here is the quick way to do it.
you take the exponent of “t” and turn it into the coefficient (multiplied by any coefficients already there) and then decrease the exponent by one. Example y=x^4+2x^2
The derivative would be y’=4x^3+4x
Try it.
