51. [unparseable or potentially dangerous latex formula]
52. Change [unparseable or potentially dangerous latex formula]to a decimal, then multiply. [unparseable or potentially dangerous latex formula]
62. Cotangent in quadrant 1 is [unparseable or potentially dangerous latex formula], so 90-38=52.
71. This is consecutive triangular number reciprocals starting after 1/3. Take the sum of all of the triangular reciprocals at that point (last term divided by second to last term) and subtract the sum of the ones which are not included.
[unparseable or potentially dangerous latex formula]= 5/7
[unparseable or potentially dangerous latex formula] 3/5

I don't get what I am doing wrong on this question: 6^5 / 4 has a remainder of :
Also can u help on the simplified coefficient of the xy^2 term in the expansion of (x + 2y)^3 is :

I guess this signature really doesn't matter now that I know that the forum is going down soon...
