Показать описание
This video is about Evaluating Inverse Trigonometric Functions (arcsin, arccos, arctan) Using Unit Circle. We discuss how to find the angle given the trigonometric value using the unit circle. We also discuss the restricted domain for sine inverse, cosine inverse, and tangent inverse and why they are restricted to these quadrants. We also go through 15 examples to give you plenty of practice!

hi, Just wanted to say that your videos are absolutely lifesaving. i was absent for 3 days in my precalculus class and knew 0% what was going on, and this video absolutely saved my grade.

doing uni maths for engineering where this is assumed knowledge which i mustve missed long ago. It has been a really challenging couple weeks and ive been so stuck, until this, because i didnt even know what i had to study to meet the prerequisites. you have saved my education, my friend. Please keep up the awesome work!

this video saved me. My online trig professor likes to put notes online and audio to explain the notes and it just was too confusing. I needed to actually see it being done. Your explanation was so easy to understand and it helped that you went through problems one by one. By the second problem I was answering before you were done explaining. THANK YOU SO MUCH

Thank you for your concise and well explained videos. I've been out of academics for 9 years or so and I'm going back to college and your videos have been amazing refreshers and reviews to get me caught back up to where I was.

Thank you! Laying the unit circle and the problems in the same board made me understand it quickly.
