Statistics and precalculus both require skills in algebra. The difference between basic statistics and precalculus is that, precalculus is more of advanced algebra. Statistics on the other hand is more computational stuff. If you are talking about basic statistics, i think it is easier than precalculus. But remember, statistics is more involved as it gets higher since it requires calculus or real analysis kind of thing, so it is difficult.
It depends. It's easier than Algebra.
My Teacher said in the begining of pre calculus it is baisically algebra 3 and geometry 2. pre calc algebra is more complicated than basic algebra. however pre calc uses that basic algebra in solving problems. so all in all, they are just different levels of algebra
They are circles whose radii are smaller than some value set by the user.
No calculus is harder, because calculus is basically a combination of algebra and trigonometry, so you need algebra to do calculus. Also, calculus involves limits, differentiation, and integration. Integration makes algebra look like kindergarten. +++ Meaningless question, ditto with the answers I'm afraid. These are not separate entities but all fields of mathematics, and you use algebra in expressing and solving mathematical problems. Calculus is NOT "basically a combination of algebra and trigonometry". You can differentiate and integrate trig. functions, but although calculus alone does not rely on trigonometry for its existence, its manoeuvres are all algebraic steps. As to comparative difficulty, that is entirely down to you. If you find algebra difficult you will find trigonometry and calculus difficult, because algebra is used to describe those two (and any other) mathematical process. Algebra is not an isolated topic!
The disadvantage of trigonometry is that it requires an intellectual effort to learn it. It is much easier to eat pizza, than it is to learn trigonometry. Put down that textbook and order a pizza. Yum!
Surely, there are more than 3. There are more than 3 subjects within maths: algebra, geometry, trigonometry, calculus and each one of them has divisions!
There is no easier method to practice your math skills other than using the algebra 2 worksheets to help. They have good samples to use to baseline your skills.
Being able to use algebra is essential to studying physics. Being good with algebra can make studying physics easier than it would be if you were not good with algebra. However, being good with algebra will not ensure that you will find studying physics to be easy.
