<![CDATA[H2 Physics and Math Discussion]]>Hi guys, feel free to post any question on Physics and Math here. Iโ€™ll try my best to help you answer the questions. Many students were caught off guard by the Mathematical Induction problem in the โ€˜Aโ€™ level exam last year. I hope it wil not happan again. P.S. I am not a full time tutor, just an engineer who is using stochastic process in my daily work and love to solve Math/Physics questions (I am more into Math than Physics)

This integral is not expressible in terms of elementary transcendental functions. It belongs to an advanced category, called Fresnel's Integrals. The answer is e^x(sqrt(x) - F(sqrt(x)).


Wow. Impressive. You were able to identify that as Fresnel Integral immediately? You must have been dealing with such stuff in and out?

Thanks for the compliment.

Thanks for prompt reply. Sorry, I have not heard about Fresnel's Integrals. Can I say this is beyond H2 9740 syllabus ?

I suppose so.....anybody attending the SIMC today? (Singapore International Math Challenges). I need to listen to the high school kids presentation tomorrow.

Good to know that there is a kind soul out there.

How to integrate (e^x)*(x^1/2) ? I tried integration by parts, but seems endless.
Checked the online solver and the answer has imaginary part in it.

Hi,


May I know how did you work out for the above answers? the detailed workings?

Thank you!
Send me an email or leave your email contact here. It's hard to type symbol on the forum. I will scan it and email you.

I have decided to remove my info and contact :-). If you are a part time/full time tutor, please try to solve your own questions. My aim is to assist students (or parents whose kids are taking H2 Math)

ii) probability that at most 2 cameras are defective = P(X=0)+P(X=1)+P(X=2) = 0.3585 + 20(0.05)(0.95)^19 + 20C2(0.05)^2(0.95)^18 = 0.3585 + 0.3774 + 0.1887 = 0.9246
iii) mean is 20*0.05 = 1; standard deviation is sqrt(np(1-p) )= 0.975

i) probability that exactly 12 cups of coffee were sold in 2 hours.
Average in 2 hours is 20 cups. Hence, P(X=12) = 0.01763

ii) probability that in an hour more than 3 cups of coffee are sold.
= 1- P(Y=0) - P(Y=1) - P(Y=2) - P(Y=3) = 0.01034

Feel free to PM me if you need any assistance ๐Ÿ™‚
