What is the integral of sin t dt with the interval x 0?
Let g(x) = interval [0, x] of sin t dt, and f(t) = sin t. Since f(t) is a continuous function, the part one of the Fundamental Theorem of Calculus gives, g'(x) = sin x = f(x) (the original function). If you are interested in the interval [x, 0] of sin t dt, then just put a minus sign in front of the integral and interchange places of 0 and x. So that, g(x) = interval [x, 0] of sin t dt = -{ interval [0, x] of sin t dt}, then g'(x) = - sin x.
It is observed that all bodies sliding down a frictionless inclined plane have the same acceleration how does its happen?
Fx=G*sin(t) = m*g*sin(t) a=Fx/m=g*sin(t) ->> does not depend on mass
Show that cos3t equals 4cos cubed t - 3cos t?
cos(3t) = cos(2t + t) = cos(2t)*cos(t) - sin(2t)*sin(t) = [cos2(t) - sin2(t)]*cos(t) - 2*cos(t)*sin(t)*sin(t) = [cos2(t) - sin2(t)]*cos(t) - 2*cos(t)*sin2(t) then, since sin2(t) = 1 - cos2(t) = [2*cos2(t) - 1]*cos(t) - 2*cos(t)*[1 - cos2(t)] = 2*cos3(t) - cos(t) - 2*cos(t) + 2*cos3(t) = 4*cos3(t) - 3*cos(t)
Given sin theta equals 7 over 13 and tan theta is less than 0 find tan theta?
sin(t) = 7/13 cos2(t) = 1 - sin2(t) = (169 - 49)/169 = 120/169 so cos(t) = ±sqrt(120)/13. But sin(t) > 0, tan(t) < 0 implies t is in the second quadrant so cos(t) = -sqrt(120)/13 And then tan(t) = sin(t)/cos(t) = -7/sqrt(120) = -0.6390 (approx).
What are the 2 sin's?
No t so sure about this
Why is sin used in the refraction of light?
Light follows the Law of Sines in refraction and reflection' sin(I)/VI = sin(T)/VT=sin(R)=VI.
The equation of rotation geometric transformation?
In two dimensions, the equations of rotation about the origin are: x' = x cos t - y sin t y' = x sin t + y cos t. where t is the angle of rotation, counterclockwise.
What is the rule for rotating figures?
To rotate a point in the coordinate plane which is represented by the column vector( x )( y )through an angle t, anticlockwise, you need to pre-multiply it by the matrix[ cos(t) -sin(t) ][ sin(t) cos(t) ].
What are the parametric equations of a hyperbola?
x = a cosh(t)y = a sin(t)gives the right side of the hyperbola.x = -a cosh(t)y = a sin(t)gives the left side of the hyperbola.where t ranges over Rsinh(t) = (et - e-t)/2cosh(t) = (et + e-t)/2
What does Dirt t brag T ar bhragadir a bheith cuimhne mhaith aige slaig bhunata agus an bmnta mean?
As a full sentence it makes no sense. "Dirt t brag" should probably be "Dúirt tú bréag". "Dúirt tú bréag" means "You said a lie" "T ar bhragadir" should proabably be "Tá ar bhréagadóir" "Tá ar bhréagadóir" means "A liar has to" "a bheith" means "to be" "cuimhne mhaith aige" means "he has a good memory" "an bmnta" should proabaly be "bómán" "slaig bhunata agus an bómán" means "basic waste ore and the fool"
What formals are used for angular and Harmonic motion?
S= theta R x(t) A sin (omeg t) Vt = omeg R At=apha R a(t) = -omega ^2 A sin (omega t) Vt= omega R
When the Height of a swing above the ground can be modelled by the equation H equals 1 plus sin Bracket 3 t Bracket and H is measured in meters and t in seconds When t equals 5 H is approximately?
H = 1 + sin(3t) When t = 5, H = 1 + sin(15) = 1 + 0.2588 = 1.26 metres, approx.
