Use the substitution cos^2 theta = 1 - sin^2 theta, and then you will get a quadratic. There is no need to bring triangles up. Because you do not know (beforehand), that there is only one solution in the given range.
Man Got (almost) all of them right I thought that triple minus meant modulo and upside down T meant false BOTH OF TJEM ARE you could just say that pi is the prime counting function |8}+|10}/10
in the f(x) one, i get what happens on the right side but how does it look like on the left? because if its y, you remove the y and then the Δy is left alone there on the left to give the equation Δy = (bunch of numbers) how can you do the same thing with f(x)? Or is there no need for it? my professor might require it for us lol
Everything is good but i have one confusion That we have to divide the rate per annum when our compounding frequency is monthly, quarterly, semi annually
