online calculators&trig questions

[ffdpsoldier]

I'm looking for online calculators, not mathway but. Ones that is aplug and play, for example I know of one were you place the side on a right triangle an 1 sides degree and it gives you all the sides and degrees. I've been having probles withthe circle side of trig. using triangles rise/run and cos, csc , sin ect. , and also a graph calculator were u plot points and get a f(x).
I've been craming a lot of trig than I'm tosed unknown questions. I would look them up but I don't know the name of the problem...... and what's the sqiggly (i) in a problem?
And does anyone understand how to solve the red n blu graph functions
Ex. F(x)=x^2. In red
G(x)= ? In blue

The "i" sounds like the imaginary number used to build complex numbers. i is the square root of -1, so i squared is -1. This is covered in the algebra courses as well. Any number can be represented as a complex number (part real, part imaginary) of the form a + bi and can be graphed on a plane as well.

When you get an assessment in ALEKS it will almost always give you questions you don't yet know. This is because it is trying to determine what you do know. Missing one means there is a section of knowledge that you haven't learned yet, and it will show you what you need to learn.

yeah I understanding throwing things at me I dont know. but i havent been in a good math "class" in 7 or 8 years , it was bugging me because i googled it and came up with nothing because it searched for the (me-i) ok so now i know.. now if a problem comes up say 5/6-5i ...... i can just do 5/6-5*-1? right

Complex number is two parts, real and imaginary. Given x=(5/6) and y=3i, the solution to x-y is just (5/6)-3i.

Unless the "wiggly i" you are talking about is given in the context (i=1 to 10) Sum/Product/whatever 2x_i where 'x_i' is x subscript i?

I'm gonna take a a break from math, I like seeing the interactive equations so I can visibly see the equation in work. I had a. Few for triangles circles,had 1 were u ploted the points on a graph andwould automaticly show the function, then allowed you to move it ploting points and would give you the function than allowed you to freely move it to find the g(x). But I've done 15hrs or so of math in the past 4 days I'm burnd out. I was thinking of getting a graphing calculator

That's a pretty horrendous schedule; definitely want to take a break. Maths is one of those subjects where it needs to be studied in small, regular doses. By this is meant, introduce new type of problem, show meaning/context of problem, show types of tools/solution to problem, practice solving problem, check working, find errors, adjust, more practice.

Everything that gets learned gets used and everything learned on day x is necessary or helpful for day x+whatever :/

I'm not one to wait, if I do, I tend to get lazy, and I don't like math,so the quicker the better.. I think I got through beg, int,and college algebra in 2 or 3 weeks, I rather cram it in and never worrie about it again, I'm going for both trig and precal at the same time. But I'm gonna break away for a week to regain sanity.
