cos(wt+theta)

@btssaay @hajmola__ Also cos is even function so wt+ theta - phi and phi -wt -theta will be same. A = phi B = wt + theta https://t.co/xkJSnh5NpE

x(t)=A cos(wt + theta).... i love physics

Wt = T/R Wr = Wt tan theta @ cos aquaman Wx = Wt tan aquaman

@btssaay They have used the identify cos(A-B) = SinASinB + CosACosb where A= wt + theta and B= ∅(phi)

Engineering is easy actually, you only have 3 steps to remember... And, in step 2 there are 5 steps while in the third step in step 2 you need to memorise 200 formula and for 80% of the formula you only need to know how to derive it which is ten pages work step.. Easy right?

@rachelmay231 ok. B/c on number 9 you wrote Ff/Fn = Wt* Sin (theta)/wt * Cos (theta) so thats why i did that.

asks v(t)i(t) = Vm.Im cos(wt+theta).... http://plurk.com/p/bvfyac

@Mandlbaur @drcirclefan6 @Scienceguy122 That equation isn't from physics it's from math. Any point (cos(theta), sin(theta)) is on a circle with radius 1. Therefore any point (r * cos(theta), r * sin(theta)) is on a circle with radius r. wt + rho increases constantly with time so it shows a constantly changing angle.

@engmar81 ما فهمت؟ القانون الي اهوه X (t)= Xmax cos (wt + theta ) ?

wt is torque acting on a pendulum ov length l inclined at an angle theta???? a.mgl b.mgl sin theta c.0 d.mgl cos theta Mcat 2011
