Arccos sqrt2/2

In using the Solve[] and the ArcCos[], I am getting sort-of two different answers see attached and cannot understand why. Would someone please explain to me why, in solving for Phi, I am getting different answers? C[1], C[1]? Answer Unmark. Mark as an Answer. View groups Follow this post. Share this post:. Get same answers using the Solve[] and the ArcCos[] commands? Mitchell Sandlin. Posted 7 years ago. Hi In using the Solve[] and the ArcCos[], I am getting sort-of two different answers see attached and cannot understand why. Reply Flag. Mariusz Iwaniuk, engineer, math hobbyist. Because is a general solution.

That's the domain. This is also asking what angle would I have to take the sine of in order to get square root of 2 over 2. And the way that-- We'll arccos sqrt2/2 restrict its range to the most natural place.

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.

Posted 9 years ago. At Regards, APD. And so we can say-- We can now make the statements that the arcsine of minus square root of 3 over 2 is equal to minus pi over 3 radians. So this is minus the square root of 3 over 2. How did Sal know that the arcsin domain had to be in between -1 and 1 at Because the sine value, the sine of this, is just this height right here. You can just check that. Because if you take the sine of any of those angles-- You could just keep adding degrees. But we just cared about the height. Tag limit exceeded.

Don Warfield. Posted 7 years ago. But if we're dealing in radians, that's not good enough. Community posts can be styled and formatted using the Markdown syntax. Ellie Anna. And say, I immediately know that sine of x, or sine of theta is square root of 3 over 2. Is there an an And where am I? Sign Up for Free. Sign Up Free. That's not the best looking unit circle, but you get the idea. But you're like hey Sal. Sign Up. This means that all the possible outputs of the sine function are between -1 and 1 in other words, the range is between -1 and 1. Let's do another problem.
