When doing this what RPM do I need to keep so the car doesn't stall or over rev and in which gear is the best.

Yo freestyle reaction i got something for you. Or anyone else solve these basic math problems.
1). iight what is e raised to the natural log of x squared?
2). whats the Intergral of sin x?
3) what is the derivative of (4x sqaured + 5) squared?
4.) what is the half angle formula for cos squared x.?
These are basic ****. YEah u can look up these identities behind your math book. lol.
Yeah intergers are negative my bad but i dont consider them negative cause when ever we use intergers we never really use em with the negatives well at least in my math study. we just say non-zero or something to denote that they are all positives.
I hate imaginary numbers which are the +- of a square root..
***********BONUS*************
For all you smartees
What is the Partial Derivative of F(x,Y) = 3x^2 + xy + 2x^2y^3..
find Fx, Fy, and Fxy....

2) donno
3)forget what a derasdiaive is
4)1+sin^2 x
If i looked through my notes i could answer every one of these. Basic Calc and Trig. But, being the lazy focker I am i dont feel like it.

1) X, e raised to Ln cancels itself out so we get just X
2) - cos x, the intergral is the anit derivative and if there is no specific limit you add the constant C.
3) 16X(4x^2 + 5) raised to the one. Here we use the chain rule.
4) 1- sin ^2 x / 2
5) Fx = 6x + y + 4xy^3
Fy= x+ 6x^2y^2
Fxy= 1 + 12xy^2
If you do the problem using implicit differnetiation there is a short cut. Take the partial derivative of x divided by the partial derivative of y which is
- Fx/Fy which gives us = - 6x + y + 4xy^3 / x+ 6x^2y^2

wel you guys did pretty well. I assume it was a long time since u guys seen this stuff. Some is calc I , II and III. Let me not give you guys and Methods of Differential Equations using Undetermined Methods of Coefficiant, variation of parameters, Laplace Transformation, Euler Power Series, taylor Powerseries, HOmogenous and Non homogenenous Problems mixed with seperable equations, last but not least Fourier Series.
