Reciprocal of Cosine is Secant
Cosine of -90 is 0.
it would be secant, 1/cosine
[ cos(Θ) ]-1 = 1/cosine(Θ) = secant(Θ)
0.525321989
Cosine(42 radians) = -0.399985 Cosine(42 degrees) = 0.743146
In radians: cos(42) = - 0.399965315 ---------------------- In degrees: cos(42) = 0.7431448255 ----------------------
It is 0.7426 approx.
It is cosine*cosine*cosine.
what is the cosine of 3.14 ?
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
Cosine is 0.995
The inverse of the cosine is the secant.
