Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

I was really starting to get down on myself because I could never answer the trig questions I was getting asked on the street.

It was a dark, stormy night. Your car broke down and you are walking to the gas station. You see a man in the distance. Clutching your umbrella, you increase your pace. As you get closer, you see the man more clearly: glasses, khakis, and a button-up shirt. You wave, trying to be nice but not trying to initiate conversation. As you pass, he steps in front of you, blocking your path.

Can't believe we have been taught all these years in science school to use the inverse function on calculator to find out angle value without explaining to us from where it comes. Thank you so much Khan academy

Can I have this dude as my PreCalc Teacher instead?

I think these videos are wonderfully informative. I appreciate their direct approach and I think this is a refreshing departure from the usual obtuse method found in the majority of textbooks.

Hey Sal! I was just curious since I started to notice a difference, did you update your software or something that you are doing these videos with? Just curious, they look amazing now, and much easier to follow!

This is great! Can you do one on finding the derivatives of inverse trig functions?

"tan= slope of a line" mind=blown O_o

your range is -pi/2 < y < pi/2. And 7pi/4 is gretaer than pi/2.

I love the "if someone were to walk up to you on the street and ask you" introduction. That's such a relatable scenario! Actually, I wish people would actually do that. Maybe a fun way of getting to know people :-)
