Arccos sqrt2/2

In using the Solve[] and the ArcCos[], arccos sqrt2/2, I am getting sort-of two different answers see attached and cannot understand why. Would someone please explain to me why, arccos sqrt2/2 solving for Phi, I am getting different answers? C[1], C[1]? Answer Unmark.

I'm in radian mode. Sort by: Top Voted. Let's think about it a little bit.

.

The arccos function allows the calculation of the arc cosine of a number. The arccos function is the inverse functions of the cosine function. Arccosine function The arccosine function is the inverse function of the cosine function , it calculates the arc cosine of a number online. The number on which you wish to apply the fonction arccosine function must belong to the range [-1,1]. To calculate the arccosine of a number, just enter the number and apply the arccos function.

We learned this in the unit circle video. And all of those would work because those would all get me to that same point of the unit circle, right? Remove Add a file to this post. You can't have a function where if I take the function-- I can't have a function, f of x, where it maps to multiple values, right? Mark as an Answer. Well that's the same as the y-height, I guess we could call it. As a side note if you want to evaluate an expression involving the arcsin, arccos or arctan then you should use a calculator. So we developed a line of study tools to help students learn their way. Suggested Textbook. And all you have to realize, when they have this word arc in front of it-- This is also sometimes referred to as the inverse sine. Video Answer Solved by verified expert. That's my x-axis. Would someone please explain to me why, in solving for Phi, I am getting different answers? And this, I think, is a much easier question for you to answer. This is theta.

For the radian thing, there seems to be times when the word 'radian' follows pi. Sign up Login. Posted 7 years ago. Later you will be introduced to the concept of a general answer This is what you will need to do for the "Evaluate inverse trig functions" exercise. So the first thing to do would be to figure out what you don't understand. So if I were to write minus pi divided by 3, what do I get? And to confirm this, let's just-- Let me get a little calculator out. That's the domain. Let me do it in this blue color. Sal introduces arcsine, which is the inverse function of sine, and discusses its principal range. But, if you take quadrants 1 and 4, then the sin function hits all possible values. Tanner P.
