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 [math]dv = dx$$ but I've stuck when its in the $$u.v - \int v.du$$...

its -2 pi ft^3min a typo error. But the implicit difference where the placing of values for numerator and denominator is correct right?

by using implicit difference where the -200ft/min is the numerator and the 100 ft is th denominator hence the answer is -1/2 pi ft ^ 3min.

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...

Yes the length of latus rectum is 2

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. $$x/1/3 + y/2/5 = 1 x/5 + y/6 =1 [/math] I made like a cross multiplication it becomes [Math] 6x + 5y = 30$$ 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...

Re: Intercept Form 3 Question Problems $$\displaystyle 3b - \tfrac{20}{3} \:=\:\text{-}\tfrac{1}{3}b \quad\Rightarrow\quad b = 2$$ To get the answer of $$\displaystyle \frac{x}{\text{-}\frac{1}{3}} + \frac{y}{2} \:=\:1$$ I have a question regarding to this solution on number 7: where did the...

Re: Intercept Form 3 Question Problems Yes, so it means "3x" or "3 times" are the same though on the given y-intercept?

Re: Intercept Form 3 Question Problems On number 7) the given of the slope is 3x, my mistaken to posted it but is there a difference on the answer?

Re: Intercept Form 3 Question Problems MarkFL: Sorry about that, well next time I'm going to post a question which is really hard for me to understand very well prior for the rules n this forum. :)

Greetings everyone, I need a help since the lecture of intercept form formula is $$X/A + Y/B = 1$$ are provied as limited examples and couldn't find exact information regarding for that. 6) Reduce the equation $$2x+3y = -1$$ to intercept form. 7) find the equation of the line whose slope is 3x...

Could I manage to have an exact 180 degrees with the formula of tangent m2-m1/1+m1m2 ? - - - Updated - - - Well nevermind, got already. Thank you for the time. :)
