Generals, Please help me with these problems :

here..
Q1

agentofchange1:


its ok bro.. n bless u too.

BTW: check my solution on question 2

correct 'dy/dx ( ysinx) to. d/dx [ ysinx] ....(line 3 or 4)

twas a mistake ...' brain solves faster than hand. '

hope u get...

Thanks , I did get it. Final answer is y = sinx/2 + kcosecx.

ladokuntlad:

If am not here to solve the questions.
I can at least help u get a textbook that will help u grow in mathematical methods.
k.a Stroud is here at ur door step

Thanks, I will it. I appreciate.

hmm.....its jackpot's birthday. still confused about her personality tho...
On behalf the maths family, HAPPY BIRTHDAY JACKPOT

here.. Q1

Thanks bos. I really appreciate for touching that.

Please help me solve this indices. If 2^n =y. Find 2

Please someone should help solve this:

SOLVE BY LAPLACE TRANSFORM, THE EQUATION

d^2 X/dt^2 +10(cos5t - 2sin5t) given that at t=0, X=1 and dx/dt = 2.

At the end, the final answer should be this: (2t + 1) cos5t + tsin5t. I have not been able to arrive at this answer. this question is in page 91 of Advanced Engineering maths fourth Edition.

check the question again , and edit Asap

Birthday problem
Use the formular Pn= Mpn \ M^n, where M is the number of days in a year. (365)

stlaibrowne:


I am 100000000000000% sure you need to read the question again. Because actually at t=60 h is not zero but h=-12000 and that's not zero. Get my point ?

Well my friend you are partly right, but your interpretation is not clear, the question says that if i look at the rocket at time t>20 i will see it at ground level, people from different fields will have different interpretation, as a physicist i would say that at h(60)=0,and the kinetic energy gained by the rocket as it reached ground level zero was dispelled into other froms of energy, including sound and heat

MathsChic:

Only a mathematician can tell such joke, cos it's all in favour of mathematicians. Funny, clever joke


Today I was thinking something. The ratio of the circumference of a circle to its diameter is a number that doesn't occur in nature any other way, besides as a ratio of circumference to diameter. Isn't that just spectacular? Or am I wrong? Does it have other occurences?

a circle is the one shape that defines creation.

I think the cross product of two or more vectors is as scalar as the dot product of the two vectors, but most mathematicians all over the world believe in it as a vector. I think there is something illogical about the general derivation of cross product.What do you think?

[quote author=Mathemagician1 post=40779133][/quote] for d 2nd question, u r to use quotient rule nt product rule.

You didn't notice that I re modified the equation. Whether you use product or quotient rule in this regard your answer is always going to be the same.

-x^-3(2sinx - xcosx) and (xcosx - 2sinx) / x^3 are the same.

waking my memory in maths

You're most welcome sir.

What course can someone study without physics?
