Thanks a bunch!

Hi all, can someone please give description about the use of composite and inverse functions with examples...? any help will be appreciated :!)

[b]1. The problem statement: QUESTION:the general solution of equation (√3 - 1)sin∅+(√3 + 1)c0s∅=2 is 1) ∅=2nπ+- (π/4)+(π/12) 2) ∅= nπ + (-1)^π (π/4)+(π/12) 3) ∅=2(n+1)π (π/4)+(π/12) The Attempt at a Solution ACTUALLY I DONT NEED THE ATTEMPT, i know the answer is option 1 , i don't...

it might be but during printing not translation.the book is in english...!

the question above is as stated as in my book..

the question demands the no. of terms only..it seems impossible to solve...:/

find no. of terms... Homework Statement find n 212,179,146,113,...... [b]3. The Attempt at a Solution here a=212 d=-33 but nth term or the sum is not given.any help will be appreciated thanks

help regarding forum rules...! ive some questions which i am unable to solve..so is there any room in this forum to post these questions or simply can i post these questions..because according to forum rules you should have some solution to a problem..moreover I've been remarked that "we don't...

thanks..

Sequences and series help... [b]1. Homework Statement 3+3a+3a^2+...∞ is = to 45/8 where a>0,then a is...? [b]3. The Attempt at a Solution since it is a g.p so using S=(a(rn-1))/(r-1) for r>1 ive all the values except for "n"..can someone help...:/

yes, this is the exact wording of the question...! is there any possibility to get 15N by amend this question a little?

A force of 5N is acting along y axis,its component along x-axis is: 5N,15N,7N,10N. Please help me in this problem as it seems incomplete to me.. F=FXCOS@,F=FYSIN@...dont know the angle as well.. The answer is 15N..

thanksss.

I need to know the whole phenomenon of circular motion. Ex: centripetal force acts or acceleration is perpendicular to tang. Acceleration etc. So i need to know the other effects as well(if exists)

when a body moves in a circular motion or a path,how many effects are possible..?
