Here is a list of 5 free websites to solve math problems online. The websites let you type all your math problems and provides step by step solutions. These websites cover all the topics of mathematics like Algebra, Statistics, Trigonometry, Geometry etc. It also covers all the levels of mathematics. From simple equations to complicated ones, it covers everything and has something for students of all age. Some of these websites also let you download worksheets.

The fifth and final website to solve math problems is Tiger Algebra. The only reason I have mentioned this website at the end is because it lets you solve only algebra problems. Other than that, it is a good website that covers all the regions of algebra. You can solve equations, fractions, linear algebra, non-linear algebra, and more. The problems have to be typed in the box provided above and you can get a step by step answer with just one click. Apart from the questions you type, you can also view answers for some of the recently solved problems on the website.

1. Easy, by induction. If a set has one element, the one element is the set s lower and upper bound. Now assume that if a set has n elements, it contains its lower and upper bounds. Let S contain n+1 elements, and let S be the set of all but one element; call this extra element x. S contains its lower and upper bounds since it has n elements. If x is larger than the lower bound in S , that lower bound is still a lower bound for S. If x is smaller than the upper bound in S , that upper bound is still an upper bound for S. If x is smaller than the lower bound in S , then x is the lower bound in S, and if x is larger than the upper bound in S , then x is the upper bound in S. (x cannot be equal to either bound, since it was assumed S was a set, and sets either contain or do not contain their members, they cannot have members more than once.) 2. I m going to assume you asked us to prove that if x is NOT in S, and x < b then there is a number y in S such that x < y. Suppose not: then for all y in S, y < x (remember, x not in S, so y=x is not possible). Thus, x is an upper bound of S. However, x < b and it was assumed that b is the LEAST upper bound, which is a contradiction. The analogous property is: Let b be the greatest lower bound of the set S of real numbers. Prove that if x is not in S and x > b then there exists a number y in S such that x > y. 3. Let x be any positive real number. Then x/r is a positive real number, and there is an integer n between x/r and (x/r)+1, inclusive; if x/r is an integer, let n = (x/r)+1, so that n > x/r. nr > (x/r)r = x, which proves that x is not an upper bound for S. Therefore, S has no upper bound.

Math word problems often intimidate students. Even to those students who are very good at Math find solving word problems difficult. This is usually because word problems require converting the problem into a mathematical equation which can be solved to arrive at an outcome. Even students who are good at Math may not always be good reading a problem and arriving at an equation. Also Word problems need a different strategy than regular math sums. To become confident and successful word problem solvers, students must be taught good problem solving strategies.

I m not sure what w0t is, and I m not sure why this requires more than high school trigonometry. But anyway: Taking the second one first, R and r have to be the same. Why? Because cos and sin both have range [-1,1]. As for the rest, if I ask you to find an a such that for all x, cos(x) = sin (x+a), you can do that, right? Well, then theta = sigma + a :) For the first one, A = -r sin (theta) and B = r cos (theta). (Why?) To reverse engineer that -- well, what does A^2 + B^2 equal? That tells you r. And you can find theta immediately from there.
