I'm saving the world: one question at a time.
How do I find the derivative of the integral of ln(t^2 + 1)dt from 0 to x^2?
The answer is 2xln(x^4 + 1)
1 AnswerMathematics9 years agoHow would I take the integral of e^(2x) * square root (e^x + 1)?
Please help me! The answer is (2/5)e^(5/2x) - 5e^(3/2x) + c

4 AnswersMathematics9 years agoHow do you get the two sides in this inequality? 78 >= 80 - 10cos(pi(t)/12)?
78 >= 80 - 10cos(pi(t)/12)
10cos(pi(t)/12) >= 2
cos(pi(t)/12) >= 1/5
1.369 =< pi(t)/12 <= 4.914
5.23 =< t <= 18.77
I don't understand where the two sides in 1.369 =< pi(t)/12 <= 4.914 come from
1 AnswerMathematics9 years agoHow would you find the limit of this?
Limit is as h approaches 0... the function is [cos(3pi/2 + h) - cos(3pi/2)] / h
I do notice that this does look like the definition of the derivative, but I do not know how to apply that knowledge to the problem.

A particle travels along a straight line with a velocity of v(t)=3e^(-t/2)sin(2t)
meters per second. What is the total distance, in meters, traveled by the particle
during the time interval [0,2] seconds?
(a) 0.835
(b) 1.850
(c) 2.055
(d) 2.261
(e) 7.025
The answer is D. But I keep getting B.

3 AnswersMusic & Music Players1 decade agoIn algebra (II), for quadratic functions, can a horizontal stretch be outside of the x^2?
The problem is asking me to horizontally stretch by a factor of 2 but my choices are only g(x)=1/2(x)^2 or g(x)=2(x)^2
Obviously I think my answer is g(x)=(1/2x)^2
