WebDec 28, 2024 · In rectangular coordinates, the point on the graph at θ = π / 4 is (1 + √2 / 2, 1 + √2 / 2). Thus the rectangular equation of the line tangent to the limacon at θ = π / 4 is y = ( − 2√2 − 1) (x − (1 + √2 / 2)) + 1 + √2 / 2 ≈ − 3.83x + 8.24. The limacon and the tangent line are graphed in Figure 9.47. WebThe general form of the equation of a straight line is a x + b y + c = 0. Consider two lines l 1 and l 2 having the slopes m 1 and m 2, respectively. 19. If two lines l 1 and l 2 are parallel, then m 1 = m 2. 20. If two lines l 1 and l 2 are perpendicular, then m 1 × m 2 = – 1. 21. The angle θ from l 1 to l 2 is tan θ = m 2 – m 1 1 + m 1 m 2 22.

WebInstead, think that the tangent of an angle in the unit circle is the slope. If you pick a point on the circle then the slope will be its y coordinate over its x coordinate, i.e. y/x. So at point (1, 0) at 0° then the tan = y/x = 0/1 = 0. At 45° or pi/4, we are at an x, y of (√2/2, √2/2) and y / x for those weird numbers is 1 so tan 45 ...
