Explanation:

1. x+1x=7. Multiply both sides by x to get:
2. x2+1=7x. Subtract 7x from both sides to get:
3. x2−7x+1=0. To solve this I would like to complete the square, but multiuply by 4 first to avoid some fractions:

Originally Answered: Why is it so hard to grasp the concepts of calculus? It’s because the algebra and trig and geometry skills needed are not there. The foundation of your mathematics is very low. The basics of Calculus are very easy if you are strong at the subjects that come before it.

I skipped trig and went on to take higher level calculus classes just fine. You will need to learn the concepts but I was able to pick them up easily enough as I went along. If you trust yourself to learn quickly then go ahead and skip trig.

Precalculus, which is a combination of trigonometry and math analysis, bridges the gap to calculus, but it can feel like a potpourri of concepts at times. Now, most students agree that math analysis is “easier” than trigonometry, simply because it’s familiar (i.e., it’s very similar to algebra).

The standard curriculum presents Trigonometry before Calculus. This is because Trigonometry is a good application area of calculus. The standard curriculum presents Trigonometry before Calculus. This is because Trigonometry is a good application area of calculus.

Trigonometry is hard because it deliberately makes difficult what is at heart easy. We know trig is about right triangles, and right triangles are about the Pythagorean Theorem. About the simplest math we can write is When this is the Pythagorean Theorem, we’re referring to a right isosceles triangle.

Trigonometry is a root of many future maths and decisions you will encounter, while statistics is a completely different branch that is more difficult to build off, in your case.

Contemporary Mathematics

Pre-calculus is more of a foundational math course whereas statistics is more of an elective. Statistics is exactly what it sounds like. I would think AP Stats would be more beneficial than PreCal for a Psychology major, but there is a good chance colleges will have you take a Calculus course, so I’d recommend PreCal.

However, you should not skip AB. This is because AB calculus covers the basics of calculus, such as limits, derivatives and integration (basic). This will be applied in BC Calc. When you start a semester long BC course like me, you jump right into L’Hopital’s rule.

BC Calculus includes everything in AB Calculus, plus a few extra topics. You’ll actually get an AB Calculus sub-score when you take the BC exam. So Calculus BC is not necessarily more difficult than Calculus AB. BC Calculus has to move faster because it covers more material, which is what makes it more intense than AB.
