Given the Value of Secant Find the Angle

👉 Learn how to evaluate the inverse of reciprocal trigonometric functions. Recall that the reciprocal trigonometric functions are given by the ratio of 1 and the corresponding trigonometric function. When an angle is unknown but the value of one of the reciprocal trigonometric functions of the angle is known, we can evaluate the value of the angle by first converting the given reciprocal trigonometric function to the corresponding trigonometric function and then using the inverse trigonometric function of the obtained trigonometric function.

For instance, if we know that sec x = a/b where x is unknown and a, b are known, then we an evaluate x by first expressing sec x = 1 / cos x = a/b, this means that cos x = b/a and thus x = arccos (b/a).

that's why I like to keep my videos short.

Awesome, I love how this video specifically answered the question I was looking for. I didn't have to watch a whole lecture just to find the q. I was looking for. Thanks a lot!!

I know this is an old video but thank you for all of your content, you've helped me understand things so many times when my college professors don't teach, they just silently work through the problem and say, "everybody okay with this?" and move on.

THANK YOU! I literally cried for 10 minutes about not being able to figure this out but this video explained it perfectly.

Best video on this. Short simple to the point. Thanks.

Mr Brian can these problem be solved almost as that one
If sec (theta)= 2 with 0<theta< pie/2, find the remaining five trigonometric ratios.

ten bucks says that you told some guy "How do you like them apples?" but unfortunately the Laws of Good Will Hunting did not apply at the time.

What happens if the angle is not one of the special ones listed on the circle

Thanks for this!!!easy to understand :)!
