What is cos(22) in physics?

In physics, cosine function is used to determine the x-component of a vector. So cos(22) in physics would give you the x-component of a vector that makes an angle of 22 degrees with the positive x-axis.

Express all the trigonometric ratios of cosA?

sin = sqrt(1 - cos^2)tan = sqrt(1 - cos^2)/cossec = 1/coscosec = 1/sqrt(1 - cos^2)cot = cos/sqrt(1 - cos^2)


What dies COS stand for on calculator?

"COS" stands for "Cosine", which is one of the 6 trigonometric functions. Similarly, "SIN" stands for Sine, and TAN stands for Tangent.


Use trigonometric identities to write each expression in terms of a single trigonometric function or a constant. simplify cos t sin t?

Thanks to the pre-existing addition and subtraction theorums, we can establish the identity:sin(a+b) = sin(a)cos(b)+sin(a)cos(b)Then, solving this, we getsin(a+b) = 2(sin(a)cos(b))sin(a)cos(b) = sin(a+b)/2a=b, sosin(a)cos(a) = sin(a+a)/2sin(a)cos(a) = sin(2a)/2Therefore, the answer is sin(2a)/2.


Why in dot product you use cos and in vector product sin?

We use the dot product cos and in vector we use the vector product sin because of the trigonometric triangle.
