Answer 1

H1 = (x*(1+x^2)*(1+2*x)^2)^2.3 / -log(abs(tan(y))) + (-log(abs(tan(y)))-x) /(x*(1+x^2)*(1+2*x)^2);
R2 = sinh(sqrt(2*x+(sin(y)^2))/((x+log(abs(tan(y))))^1.3 + abs(x)))-(x+log(abs(tan(y)))+cos(y))/(2*x +(sin(y)^2))^(1/3);

Assuming that ctg is supposed to be cotangent, those will need to be changed from tan(y) to cot(y).

If x and y are vectors and not scalars, many of operations here will need to be changed to element-wise.

H1 = (x.*(1+x.^2).*(1+2*x).^2).^2.3 ./ log(abs(cot(y))) + (log(abs(cot(y)))-x) ./(x.*(1+x.^2).*(1+2*x).^2);
R2 = sinh(sqrt(2*x+(sin(y).^2))/((x+log(abs(tan(y)))).^1.3 + abs(x)))-(x+log(abs(tan(y)))+cos(y))./(2*x +(sin(y).^2)).^(1/3);
