All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.
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)
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.
cosine (90- theta) = sine (theta)
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).
Cosine squared theta = 1 + Sine squared theta
No, they do not.
It is 1.
No, it is not. To be correct, the expression requires parenthesis, which are missing.
Sine(A+ B) = Sine(A)*Cosine(B) + Cosine(A)*Sine(B).
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
because sine & cosine functions are periodic.
6,561 (i solved it by using this sentence: (9x9) x (9x9)= 81x81=6,561
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
The maximum of the sine and cosine functions is +1, and the minimum is -1.
