$$\int sec(x) dx$$
1285 divided by 18
x=y'+ 2xy = 1n(x), y (1) = 2
y = X^2/3 + 0.9sin (kx) √3-x^2
6 9 over 10 divide 3 over 8
Evaluate : tan2 60º - 2 cosec2 30º - 2 tan2 30º.
5^4/25
consider the inequality x/3 + 2 < x+1/3
prove that
for all x [P(x) or Q(x)]
for all x [not Q(x) or S(x)]
for all x [R(x) implies not S(x)]
there exist x not P(x)/ther...
prve that
there exist x not P(x)/there...
