Trying to integrate: cos2x sin x dx
Substitute y = cos x
Then dy = -sin x dx
So the integral becomes: -y2dy
Integrating gives -1/3 y3
Substituting back: -1/3 cos3x

Which angle has a negative sine and a positive cosine?
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.
Is 35 degrees cos or sin?
Every angle has a sine and a cosine. The sine of 35 degrees is 0.57358 (rounded) The cosine of 35 degrees is 0.81915 (rounded)
Is sin squared theta and sin theta squared the same?
Your question is insufficiently precise, but I'll try to answer anyway. "Sine squared theta" usually means "the value of the sine of theta, quantity squared". "Sine theta squared" usually means "the value of the sine of the quantity theta*theta". The two are not at all the same.
What is cos 90 minus theta?
cosine (90- theta) = sine (theta)
Is the inverse function of secant is the cosecant function?
No. The inverse of the secant is called the arc-secant. The relation between the secant and the cosecant is similar to the relation between the sine and the cosine - they are somehow related, but they are not inverse functions. The secant is the reciprocal of the cosine (sec x = 1 / cos x). The cosecant is the reciprocal of the sine (cos x = 1 / sin x).
What is cosine squared theta equal to'?
Cosine squared theta = 1 + Sine squared theta
Do the equations sine plus cosine and sine squared plus cosine squared both equal 1?
No, they do not.
What is sine squared theta subtract six cosine squared theta divided by one minus seven cosine squared theta?
It is 1.
1 minus 2 cosine squared divided by sine cosine is equal to tangent minus cotangent?
No, it is not. To be correct, the expression requires parenthesis, which are missing.
If two integers have the same sign what is the sine of their sum?
Sine(A+ B) = Sine(A)*Cosine(B) + Cosine(A)*Sine(B).
How do you find the cosine and the sine?
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
What are the Differentiate the sine wave and cosine wave?
The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.
How does the tangent function relate to sine and cosine?
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
Why are sine and cosine functions used to describe periodic?
because sine & cosine functions are periodic.
What is sine squared times sine squared?
6,561 (i solved it by using this sentence: (9x9) x (9x9)= 81x81=6,561
How do you find sine cosine and tangent of 210 degrees?
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
What is the derivation of the wave function?
A simple wave function can be expressed as a trigonometric function of either sine or cosine. lamba = A sine(a+bt) or lamba = A cosine(a+bt) where lamba = the y value of the wave A= magnitude of the wave a= phase angle b= frequency. the derivative of sine is cosine and the derivative of cosine is -sine so the derivative of a sine wave function would be y'=Ab cosine(a+bt) """"""""""""""""""" cosine wave function would be y' =-Ab sine(a+bt)
