You are so underrated, thank you for the help!

The table with sin cos and tan with degrees and radians really helped me with this topic. Check it out at 7:25

thanks for the video! But I have a question: why do you have to have twice as many answers when you have 2x? What does the graph look like? Thanks

Edit: never mind I got it. The graph has twice as many oscillations when you multiply x by 2, so there's twice as many solutions between 0 and 2pi

Damn you really are a math genie, made my wish of understanding trig come true

Hello SIR! Your videos helped me go from a Z+ to and E-, I'm so ungrateful

Damn bro thank u sm for this😭😭 everyone in class was doing questions on questions and I couldn’t even solve one but now I finally understand THANK U😭

[abduljamal]

Does that table work all the time....? What if you are using negative values as first angle or arcsin(x) = -45?

I could cry. I finally understand trignometric equations!!

At 3:08 when u did the second one why can't you just do 540-143.1?? Sm1 pls explain

[ahmadjawadeosmani]

How do you change from degrees to radians
