## Task list for editors[edit source]

please fix these:

- the exteral link "18.01 Single Variable Calculus" is broken (FIXED)
- the quiz is on trigonometry. not calculus* (*Because you must first understand trig to be able to comprehend calculus, I.E. - Calculus is partly based upon trig) (I have included explaination text and link to Trigonometry)
- introduction MUST start with "what is Calculus"? because it's the first question one asks if comes here ramdomly or as a start. and I thought it's physics after reading the first lesson.* (* This link on the page covers this Welcome to "Introduction to Calculus")
- If you can pass this quiz, you are ready to take this course...SO WHAT DO I DO IF I CANNOT PASS THE QUIZ??? WHERE DO I GO?? THIS IS NOT CLEAR.* (*Agreed, there should be a link to trigonometry) (Link and explaination text done)

User:Graemeb1967/Introduction to Calculus

Mikeb beat me to it! His first 3 answers look correct to me.

Check my answers for part 4.

I have tried using math formating with my solutions which I will keep pursuing as time permits.

## First Problem[edit source]

Shouldn't we lose the **cos X** from the solution

aka instead of **tan X = sin X / cos X**

use **tan X = sin X / ± SQRT( 1 - sin ^{2} X )**
