WebDec 26, 2009 · Because sin-1, cos-1 and tan-1 are the sine inverse, cosine inverse and tangent inverse functions. Csc (x), cot (x) and sec (x) are the reciprocal functions of the sin (x), tan (x) and cos (x) functions. Not the inverse of them. Offline. Websin stands for sine.cos stands for cosine. cosine is the co-function of sine, which is why it is called that way (there's a 'co' written in front of 'sine').Co-functions have the relationship sin@ = cos(90-@) However, the trig function csc stands for cosecant which is completely …

WebHow do you simplify the expression cscxcscx −sinx ? = cos2x Explanation: cscxcscx− sinx = cscxcscx − cscxsinx = 1−sinx× sinx ... What is the equation of the normal line of f (x) = sinx1 + cscx at x = 6π ? y = 4 31 x− 24 3π −96 3 Explanation: The function can be written as f (x) = cscx+cscx = 2cscx ... WebTrigonometric Identities. Trigonometric identities are equations involving the trigonometric functions that are true for every value of the variables involved. Some of the most commonly used trigonometric identities are derived from the Pythagorean Theorem , like the following: sin2(x) + cos2(x) = 1. 1 + tan2(x) = sec2(x) cyndi hell\\u0027s kitchen
