What is the relationship between radian steradian degree?
if alpha is the solid angle subtended by a cone and theta is the 2d projection angle of this solid angle...Then----(both alpha and theta are in radians then) cos(theta) = 1 - (alpha/2*pi)
What is Angular velocity equal too?
Angular velocity is equal to the change in theta / change in time theta equals the arc length/ radius
Why sin integral is cos?
sin integral is -cos This is so because the derivative of cos x = -sin x
What is cos(33)?
If the angle is measured in degrees, then cos(33) = 0.8387, approx.
What is the range of cos 2x?
7
How do you simplify tan theta cos theta?
Remember that tan = sin/cos. So your expression is sin/cos times cos. That's sin(theta).
How do you simplify cos theta times csc theta divided by tan theta?
'csc' = 1/sin'tan' = sin/cosSo it must follow that(cos) (csc) / (tan) = (cos) (1/sin)/(sin/cos) = (cos) (1/sin) (cos/sin) = (cos/sin)2
What is sec squared theta times cos squared theta minus tan squared theta?
Tan^2
What is cos 360 minus theta?
- cos theta
What is cos theta minus cos theta times sin squared theta?
cos(t) - cos(t)*sin2(t) = cos(t)*[1 - sin2(t)] But [1 - sin2(t)] = cos2(t) So, the expression = cos(t)*cos2(t) = cos3(t)
How do you solve theta if cos squared theta equals 1 and 0 is less than or equal to theta which is less than 2pi?
cos2(theta) = 1 so cos(theta) = ±1 cos(theta) = -1 => theta = pi cos(theta) = 1 => theta = 0
Force times distance is?
A - WORKWork = F.s cos (theta)
De Morgan's law in complex number?
(Sin theta + cos theta)^n= sin n theta + cos n theta
What is the identity for tan theta?
The identity for tan(theta) is sin(theta)/cos(theta).
What is sec theta - 1 over sec theta?
Let 'theta' = A [as 'A' is easier to type] sec A - 1/(sec A) = 1/(cos A) - cos A = (1 - cos^2 A)/(cos A) = (sin^2 A)/(cos A) = (tan A)*(sin A) Then you can swap back the 'A' with theta
What is cos theta multiplied by csc theta?
It is cotangent(theta).
What is Cos Theta minus Cos Theta?
Zero. Anything minus itself is zero.
