Greetings :)
Well I wanted to seek help if my solution is on the right path, given as follows:
1) \int cos ^2x dx
So my solution follows like this:
u = cos^2x
du = 1/2 (1+cos(2x))
v = x
dv = dx
but I've stuck when its in the u.v - \int v.du
cos^2 (x) - \int...
Greetings everyone in MHB. :)
Well I've just created a thread to just verify if my answer is correct. On a simple problem that using implicit differentiation.
A cylindrical tank of radius 10 ft is having drained with water at the rate of 200 f^3/ min. How fast is the height of water changed...
Greetings, I‘m trying to analyze the given of directrix x = -1, axis y = 2, and latus rectum as 2
I believe there‘s two possibility equations.
I‘m not sure for finding the vertex since I got between ( -.5, 0) and origin itself.
I'm not sure on how the "invert and multiply" works.
x/1/3 + y/2/5 = 1
x/5 + y/6 =1 I made like a cross multiplication it becomes
6x + 5y = 30 then made an LCD to obtain the
Here's my progress, in letter a)
is it an M as slope only? not the whole equation? because the answer of my M is 2.
Then on letter B my equation answers as 6x+5y-30=0?
Hello, I'm here for another related intercept form problem of the formula: \displaystyle \frac{x}{a} + \frac{y}{b} \:=\:1
a) Find the equation of the line passing through (-5,-7) AND with y-intercept 3.
b) Find the equation of the line passing with x-intercept 1/3 and y-intercept 2/5.
I'm not...
