Given the inclination angle α of the straight line, find the slope of the straight line! (1) α = 30 ° (2) α = 120 ° (3) α = 5 / 6 π (PIE) A total of 3 questions, each question 5 reward points
Given the inclination angle α of the straight line, calculate the slope of the straight line
k=tanα
(1) α = 30 ° k = Tan 30 ° = root 3 of 3
(2) α = 120 ° k = tan120 ° = - radical 3
(3) α = 5 / 6 π (PIE) k = 5 / 6 π = - 3 root sign 3
