NMAT Review: Quantitative Reasoning
Question and answers already passed
Solving fractions in fractions - correct answer ✔Resolve the innermost
fraction first, then work your way out.
imaginary numbers - correct answer ✔i x i = -1
Sum of infinite sequence formula - correct answer ✔S(infinity) = a/(1-r)
Where -1 < r < 1, and stands for the common ratio
a - first term
Inverse functions - correct answer ✔Switch the x and y variables and solve
for y.
Trig identities (sin, tan, cos, csc, sec, cot) - correct answer ✔sin - y/r
cos - x/r
tan - y/x
csc - 1/sin
sec - 1/cos
