@@godnotavailable2094 Lmao yeah, I am even in a shitter position, I am doing it online so I gotta read some boring long texts and understand all concepts without really having any lecture classes, cant understand shit
It's amazing how much you can teach in 6 minutes, I love how intuitive your math lessons are and how concepts that many struggle with end up being more simple than you thought originally.
All I want to say is that you've helped me for almost 3 years now, there is nothing you cant explain clearly. Thank you so much for always being there. You are an amazing human being.
i love you i love you i love you i love you ive literally been crying for 6 hours working on this assignment for online summer school and ive always sucked at trig and i was prepared to kiss my 90 average away until I found this thank you thank you thank youuuu
Jesus dude, you really saved my ass here especially not knowing whether to put 2Pi or just pi. You really explained it well. Once again, I thank you. No really, you saved me.
Thank YOU!!!! My professor did not make any sense at all...I kept asking him why the period for 4cos^2(x)-1=0 was pi, and he said because of the identity of cos2(x), which didnt make sense to me. Now I understand how to combine the answers. thank you! Btw would it be correct to write all four answers as x= (solution)+(2pi)n (1 for each) or should we combine them ?
I dont know what it is about your explanation but its probably because it's not a half a** explanation like my professors, thanks my man we got that trig test tomorrow.
Mario, this video is cut in half! It ends at a VERY inopportune moment, right when you are about to explain to us how to handle a coefficient on x in a sin(x) situation.
Really nice . Please solve se more difficult examples for practice. These examples are also difficult but not very much please make a video of more examples.
At about 5:15-5:34, you somehow came up with -1/2. I couldn't follow how you did that. I'm an old man (53) trying to relearn math to help my niece, but I find myself stymied...I'm speaking about your 7 minute (exactly) video. Thanks.
Andre this more recent video I filmed may help you more: Solving Trigonometric Equations (Multiple Types) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-j76EIfxFb7U.html
In the last equations, isn't there supposed to be a second solution which should be 5pi/12 + pi/3n? since tangent is positive in the first and third quadrant? Thank you for the video :)
Please help me solve these questions: 1). Simplify 2cosxcos2xsin3x - 2sinxsin2xsin3x 2) Eliminate k from the equation x=sink + cosk, y=sink - cosk 3) Solve the equation 5sinx - 12cosx = 12, for the values of x from 0° to 360° inclusive

I’d convert sin^2 x into 1 - cos^2 x and substitute cos2x into 2cos^2 x - 1 then everything will be in terms of cos x and you can factor and set the factors equal to zero.
