WebWhereas, c s c is the reciprocal of sin and is written as: csc x = 1 sin x It can also be written as: csc x = sin x - 1 It is evident that the inverse of a function is different from the reciprocal of the function. Therefore, inverse sin is not the same as c o s e c. Suggest Corrections 0 WebNotice in particular that sine and tangent are odd functions, being symmetric about the origin, while cosine is an even function, being symmetric about the y -axis. The fact that …
finding csc given sin - Mathematics Stack Exchange
WebYou cannot have two different things written the same way. You seem to be confusing the inverse with the reciprocal. If sin (θ) = x, then arcsin (x) = sin -1 (x) = θ sin (arcsin (x)) = x and arcsin (sin (θ)) = θ This is the inverse function. If sin (θ) = x, then csc (θ) = 1/sin (θ) = 1/x This is the reciprocal value. WebNov 19, 2024 · csc A = 1 / (sin A) Guess what! That’s the last trig identity you have to memorize. (You’ll probably find that you end up memorizing certain other identities without even intending to, just because you use them frequently. But equation 5 makes the last ones that you’ll have to sit down and make a point of memorizing just on their own.) cable trading
