Given the inequality:
sin(t)<31To solve this inequality, we must first solve the corresponding equation:
sin(t)=31Solve:
Given the equation
sin(t)=31transform
sin(t)−31=0sin(t)−31=0Do replacement
w=sin(t)Move free summands (without w)
from left part to right part, we given:
w=31We get the answer: w = 1/3
do backward replacement
sin(t)=wsubstitute w:
