Solve for the unknown variable. Multiply the unknown x to both sides to get x cos 75 degrees = 3. Now divide both sides by cos 75 degrees to isolate x; you get The cos 75

Starting from 0° and progressing through 90°, cos (0°)=1=. The subsequent values, cos (30°), cos (45°), cos (60°), and cos (90°) follow a pattern such that, using the value of cos (0°) as a reference, to find the values of cosine for the subsequent angles, we simply decrease the number under the radical sign in the nu See more

The app is very good for solving Maths And very fast, 11/10 remarkable for cheating on homework and complex math problems just take clear pictures and you should be good. Doesn't have any problem with freezing or anything, but this one got me without a choice, the graph function is amazing and helps alot with my work on products of three binomials.

Iy has helped me so much in understanding my work, i highly recommend it, kind of crazy how powerful this calculator is, i LOVE this it helps me on homework so I can understand what I need to do to get the answer and the best thing is that it has no ads.

This app is a life saver! The answer and method is given to you in order, the explanations don't take turns and it surely doesn't waste your time! a friend from school recommended this app to me and I've got so much more done in the little time I have.
