Okay, I tried squaring both sides and I got 16/(4-t) = 0. Is that t suppose to still be in the problem? I'm guessing that I have to eventually solve for t since the answer is t = 8/3. I'm assuming maybe I've done this problem incorrectly...
Homework Statement
Find any critical numbers of the function
Homework Equations
sin^2 x + cos x
The Attempt at a Solution
I actually have a sort of silly question. Woud sin^2 in the equation be solved using the differeniation rule of d/dx[sin x] = cos x or d/dx [sin u] = (cos...
Homework Statement
Find any critical numbers of the function
Homework Equations
g(t) = sqrt (4-t) , t < 3
The Attempt at a Solution
I'm not really sure how to find a critical number when square roots are involved. I do know typically when finding the critical number you find the...
t3 + 3t2 - 12t + 4 / t3 - 4t , as the limit of t approaches 2
I figured out that that I can get my denominator all the day down to t (t + 2)(t - 2), so I figured that there must be a way to pull that factor out of the numerator.
Okay, basic question. I'm working a limit problem and trying to factor part of my fraction:
t3 + 3t2 - 12t + 4
Isn't there a way to combine like terms or something? I feel embarrassed asking this lol.
I'm having trouble understanding the problem:
Find the largest open interval, centered at x=3, such that for each x in the interval the value of the function f(x) = 4x - 5 is within 0.01 unit of the number f(3)=7
The solutions manuel goes on to say that the abs[f(x)-f(3)] = abs [(4x - 5) -...
I was working on the following problem:
An electron and a positron each have a mass of 9.11 x 10-31 kg. They collide and both vanish, with only electromagnetic radiation appearing after the collision. If each particle is moving at a speed of 0.30c relative to the laboratory before the...
