i'm new to all this so bear with me if i'm asking a question that has been asked before!
i'm in the second year of a maths and stats degree but i have to admit my calculus is terrible!!
i need to work out an error analysis in a triangle using partial differentiation and i'm only given the length of the 3 sides.
i know how to do the analysis but i can't figure out how to partially differentiate heros formula
area=square root (s x (s-a)x(s-b)x(s-c)) where a,b,c are the sides of the triangle and s = (a+b+c)/2
can anybody help?
p.s. i know the answer because i've put it inot maple but my lecturer wants to see it done by hand!!
