They are complementary functions of each other. cos hypotenuse q= hypotenuse sec adjacent q= opposite tan adjacent q= adjacent cot opposite q= Unit circle definition For this definition q is any angle. sin 1 y q==y 1 csc y q= cos 1 x q==x 1 sec x q= tan y x q= cot x y q= Facts and Properties Domain The domain is all the values of q that can be plugged into the function. sinq, q can be any May 14, 2009 · SOHCAHTOA is a VERY helpul way of figering out when to use not only Sin, Cos and Tan, but also Sin-1, Cos-1 and Tan-1. Pretty much, you break up the word into 3 parts. SOH CAH TOA. Each letter stands for a word. The first letter of each of the 3 parts stands for Sin, Cos and Tan. So for example, SOH starts with an 'S' which refers to Sin. Solve your math problems using our free math solver with step-by-step solutions.

The domain of the inverse cosine is [ − 1, 1], the range is [ 0, π]. It is an even function. Solve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. d/dxcos^(-1)(x) = -1/sqrt(1 -x^2) When tackling the derivative of inverse trig functions. I prefer to rearrange and use Implicit differentiation as I always get the inverse derivatives muddled up, and this way I do not need to remember the inverse derivatives. If you can remember the inverse derivatives then you can use the chain rule.

Let y=cos^(-1)(x) <=> cosy=x Differentiate Implicitly cos(sin 1(x)) 2 = 1 x2 + cos(sin 1(x)) 2 = 1 cos(sin 1(x)) 2 = 1 x2 cos(sin 1(x)) = p 1 x2 Now the question is: Which do we choose, p 1 x2, or p 1 x2, and this requires some thinking! The thing is: We deﬁned sin 1(x) to have range [ˇ 2; ˇ 2] so, cos(sin 1(x)) has range [0;1], and is in particular 0 (see picture below for more clariﬁcation Introduction. When x represents a variable, the inverse cosine function is written as cos − 1. ⁡.

Dans ton cas, au dessus de la touche cos, en écriture jaune tu devrais trouver soit "arccos" sois "cos-1". Je suppose que c'est arccos sinon tu n'aurait pas posé la question. Arccos correspond a cos-1. Donc tu fait arccos(2.4/7.4) pour trouver l'angle DBC
