This is a excellent app. 100% has helped me understand and learn by seeing the answer and working my way backwards. It really helps me understand the work I've been set. Very nice application Student must try for their doubts, if you have math class and you can sneak your phone to the test, I can promise this will be the single best app for you.
It helped me with alot of things like my module, homework, math, measuring, etc. Really time efficient in helping me with homework, all you have to do is take a picture of the problem then it shows you the answer, i got this app to use for homework, and I was not let down. Super amazing I am a student in math and this will get me higher grades for sure I will definitely recommend this.
Super app, would be better if you could watch an ad which in turn would make the app more money, very good, it even explains how they got the answer instead of just solving it and leaving u clueless on how to solve it. I'm enjoying with my solution and for my subscription it was so fun it also helping me how it is for true kindness I am top class in mathematics gesture.

Solution : Equation of the given curve is 9x2- 5y2 = 31 18 x - 10 y (dy/dx) = 0 10y (dy/dx) = -18 x dy/dx = -18x / 10 ==> -9x/5 Slope of tangent at the point (2, -1) m = -9 (2)/5 ==> -18/5 So, the
