• Can the new content for physics for India be found in the general physics subject as well?

• I think Okapi is right. You will probably need to learn calculus to find the instantaneous speed

• I don't think all the steps I used can be found on Khan Academy

• I disagree. There are infinitely more answers. For example, if you use u=(pi) , the equation also works, where both sides equal 0. All possible angles for u can be represented as the following, whe...

• I had the same problem. If you want, you can just skip the section and move on until you learn combinatorics in precalculus, and then go back to this section. You could also learn them right now by...

• I don't know if they will add this, but in the meantime, perhaps you could go through the science content and align it with the curriculum or syllabus your son's school has.

• Do you mean having to click on the box to be able to type in your answer? If you don't want to use your mouse, maybe using the "tab" button will work.

• I think this is a great idea. Maybe the hidden version can hide the code and prevent others from bringing up the source code in case the creator doesn't want spin offs to maximize privacy. Or, user...

• You are taking the cube root of the expression (3x-5)^3. That means you are finding the expression you need to multiply by itself 3 times to get (3x-5)^3, which is just (3x-5). 2(3x-5) is just 2 ti...

• Since you're multiplying them, you have to add the exponents (the images don't work by the way). We get each fraction into equivalent forms with common denominators: (3/4) = (9/12) and (1/3) = (4/1...
