Let θ be an angle in standard position such that cotθ=-4/3 and sinθ<0.

Determine the exact value of sec θ

Determine the number of solutions for (asinx-b)(acosx-a)(bsinx+a)=0

where 0≦x＜2[tex]\pi[/tex], if 0＜a＜b.

A fair coin is tossed 60 times. Using the normal approximation to the binomial distribution, calculate the probability that a head will show between 32 and 36 times.

Please give me as many explanations as possible~ thanks
