Hello again! I tried to make a picture out of what you have explained. Please check if I'am on the right track here. $B\pi$ the area of rectangle in blue. $C$ is the red/green area $B(2\pi-\pi)-C$ the area of brown part.

Hello MarkFL! I kind of find it difficult to understand why the area in effect is equal to the area of a rectangle? And also the part where the area above and below cancel each other? Because in your graph it has an offset of B. As I understand it, they will only cancel each other if there was...

Hello. I was having a hard time determining how the formula for the average value of the waveform can be achieved. I've read that the ave since the waveform is symmetric is (Imin+Imax)/2. I want to know how to derive it using calculus. Thanks.

Is it not that the area bounded by the function y and the x and y-axis corresponds to the y values of the integral of y? I''m still confused.

Hello! And Good day! I just want to ask why do I keep getting a negative value whenever I take a definite integral of function $$y=-50e^{-5x}$$ the graph is shown as the first image. If you look at the graph of the integral of "y" there's no traceable negative value on the graph. Why is that...

Hi kaliprasad! It did check out. But I think you made a sign error $(3a-6b+2c-3d)$ instead of $(3a+6b+2c-3d)$. How do you decide which trinomial to take first? And what if I choose $-10c^2+27cd-18d^2$? And where do you compare it to after factoring?

Decompose $$6a^2-3ab-11ac+12ad-18b^2+36bc-45bd-10c^2+27cd-18d^2$$ I noticed that the factorized form would be $$(Aa+Bb+Cc+Dd)(Wa + Xb + Yc + Zd)$$ Which is similar to the factorized form $$(Aa+Bb+Cc)(Wa+Xb+Yc)$$ $$Yc(Aa+Bb)+Cc(Wa+Xb) = c(CX+BY)$$ Is there a way that I can somehow use...

Please assist me in this problem.$\frac{2}{3}b^5-\frac{1}{6}b^3+\frac{4}{9}b^2-1$ I tried grouping but still could not find anything factorable form of the expression. Regards.

I tried it and it was too long. By any chance, do you know a faster way?

Hello! Can you teach me how to divide a smaller binary by a bigger binary. For example, 10111÷ 1110001. If you can also share tricks for a much faster solution it would be very much appreciated.

In bytes 00000001 00010001 In word 0000000100010001 In long word 00000000000000000000000100010001 Are my answers correct?

It will take 2 nibbles a 1 bit? So, 4 = 100, 2 = 010 , 1 = 001. In binary, 100010001. In nibbles, 1 0001 0001. Is this correct?

Hi markfl! digits in octal take 3 bits.

We are asked to convert the octal number 421(base 8) to nibble, byte, word and long word. Please help me how to go about it. I know that a nibble is half-byte wihich has 4 bits in it. But to cconvert an octal number to nibble is something I don't know how to do please help me. Thanks.

what do you mean? Can you show me a picture of mutually perpendicular angles? please bear with me. :) thanks!
