Csc over sec
WebOct 21, 2024 · This implies that csc trig function and cot are defined for every real number, except the ones that can be written as {eq}k \pi, {/eq} and sec trig function is defined for every real number but ... WebMar 13, 2024 · Explanation: csc stands for cosec which is equivelant to 1 sinθ. The expression is thus equal to 1 sin( 4π 3) Since we know by consulting the unit circle that sin( 4π 3) = − √3 2 we get the expression 1 sin( 4π 3) = 1 − √3 2 which can be simplified to. 1 − √3 2 = 2 −√3 = −2√3 3.

And the adjacent side, we already figure out, has length 5. So the tangent of A, which is opposite over adjacent, is 12/5. Now, we'll go the to the other three trig ratios, which you could think of as the reciprocals of these right over here. But I'll define it.
Web21. arccos x means the angle α in the interval [ 0, π] such that. cos α = x. while. sec x = 1 cos x. So arccos 0 = π / 2, while sec 0 = 1. I believe you're misled by the cos − 1 notation somebody uses for arccos. From a "function theory" point of view, the notation cos 2 x is inappropriate, because it should mean cos ( cos x); however ...
