    Yes... Look. March onwards. its the new SAT. https://collegereadiness.collegeboard.org/sat?navid=sat-nsat Januray, its old SAT with essay. just switch your date to january if you want to give the 'old syllabus' or prepare according to the new one :p

    U = sin4x Find the new limits. 1) X = π/24 U = sin4(π/24) = sin(π/6) = ½ 2) X =0 U = sin4(0) = sin(0) = 0 Differentiate the substitution. U = sin4x Du/dx = 4cos4x Find dx Du = 4cos4x (dx) Dx = du/4cos4x Now re-write the expression = ʃcos^3(4x) dx You have value of dx =...

    First step. Acceleration. As I stated in the previous question. Acceleration = (forces aiding acceleration - forces opposing acceleration)/ sum of masses Now mass of m1 is greater than the mass of m2 so we'll just assume(for now) that m1 will move down since its heavier. (If true the resule...

    If you sketch a velocity time graph. you will note that the slope of the curve will be constant since acceleration is constant. You will start from 0 (rest) and till 30m/s(final velocity) Now, Average speed = total distance/total time. Let time = t Total distance will be the area under the...

    First find the acceleration. Acceleration = (forces aiding acceleration - forces opposing acceleration)/ sum of masses Here, Block A has higher mass so acceleration will be in the direction of A. In other words A will move down. Therefore. After resolving forces you will get acceleration =...

    y = e^(-x) sinx For stationary point of any curve put dy/dx equal to 0 For dy/dx Let u = e^(-x) v = sinx u’ = -e^(-x) v’ = cosx dy/dx = vu’ + uv’ You have all the values now. Just plug in. 0 = (sinx)(-e^(-x)) + (e^(-x))(cosx) 0 = e^(-x) {-sinx + cosx} e^(-x) {-sinx + cosx} = 0 -sinx...

    Dm /dt = K(√M) cos (0.02t) dM / √m = kcos0.02t dt ʃ dM / √m = ʃ kcos0.02t dt (M ^(1/2)) / (1/2) = ksin0.02t/0.02 + c Rearrange: 2√M =(ksin0.02t)/0.02 + C Now we have t = 0 and M = 100 so just substitute inorder to find the constant C Therefore, 2√100 = (ksin0.02(0))/0.02 + C 2(10) = 0 + C C =...

    Lol, Ill try to make it short and talk to the point. You will find these drug dealers everywhere. LUMS, however, decided not to conceal it unlike so many other universities. And this depression is not because of studies. I blame the students alone. Lums is just doing what it should do. And...
