Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
60 degrees = 0.5 1/2
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
cos(37 deg) = 0.7986
The sine graph and the cosine graph are identical in shape, with the cosine graph shifted to the left by pi / 2, i.e. the sine starts at (x=0,y=0) and proceeds up with an initial slope of one, and the cosine starts at (x=0,y=1), and proceeds down with an initial slope of zero.
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
60 degrees = 0.5 1/2
Cosine of -90 is 0.
If the numerator is 0 AND the denominator is not 0, then the ratio is 0. And cosine of 0 is 1.
cosine(59 degrees) = 0.51504 (rounded)
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
Secant is 1 over cosine and cosine 0 equals 1.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
