how do you find the cosecant, secant, and cotangent on a calculator?

Question

whenever i try to do it it says error: domain

Answer 1

cosecant = 1 / sin
secant = 1/cos
cotangent = 1/ tan

Make sure your calculator is set to the right units. radians or degrees.
If your angle would give a zero in the denominator in the right side of the equations above I think it might give that error. This is because those angles aren't in the domain of those trig functions.
Try using the right side of the equations I gave and see what you get.

Answer 2

Secant Cosecant Cotangent

You do NOT want to use sin-1 cos-1 and tan-1 . Those are inverse functions, not reciprocal function. sin-1 tells the calculator to find the angle whose sine is whatever. No angle has a sine of 60, which is why you have a domain error. To find the cosecant, use 1/sin( ). To find the secant, use 1/cot( ). To find the cotangent, use 1/tan( ) So to find 100csc(60º) type in 100/sin(60º).

Answer 4

Cosecant= 1/Sin
Secant= 1/Cos
Cotangent= 1/Tan

Remember, you will get a domain error if you are trying to solve for cotangent at say, a vertical asymptote.

Answer 7

Get a scientific calculator, it has keys for trignometric values.

Cosecant = 1/sine (inverse of Sine ), Secant = 1/cosine (inverse of cosine ), Cotangent = 1/Tan ( inverse of Tan )

Answer 8

csc, sec, and cot are just the inverses of sin, cos, and tan. So if you want the cosecant of 5, just do 1/Sin5. (1 divided by sint5.) Or if you want the cotangent of 10, do the tangent of 10 and then hit the recipricol button (usu. x^-1)
You might be trying to do inverse cos, sin, and tan (ex tan-1, sin-1) etc. This is completely different.

Answer 9

You might have to look in the manual for your calculator. If you don't have one, then go to the website for whoever made it.
It might be a key that says "INV" (for inverse), or "2ND" for the other functions of those keys. If yours says error:domain, I'm assuming it's one of the TI series or something.
You need the manual to get the entries in the right order.
