Trig Graphs and Equations
Can anyone please provide the answers to these questions as this is due tomoroow. Any help would be much appreciated thanks.
(a) 2sinx = 0.2, 0o ≤ x ≤ 360o
(b) sinx + 3 = 3.5, 0 ≤ x ≤ 2π
(c) 3sin2x = 0.8, 0o ≤ x ≤ 360o
(d) sin(x – 90o) = 0.3, -180o ≤ x ≤ 180o
(e) 2sinx + 3 = 2, 0 ≤ x ≤ 2π.
(2) Solve the following trigonometric equations:
(a)tan(theta) = -1.3, 0(degrees)
(b) cos(theta) +3 = 3.1
(c)14sin(theta) = 10
(3) The fans on a windmill rotate at a constant speed.
P is the point at the end of the fan.
The height, h m, of P above the ground
at time t seconds is given by the equation:
h = 24 + 15sin t , t is measured in radians.
(a) How long does it take the point P to move from the top to the bottom of the arc?
(b) What proportion of a cycle is the point P above 30 metres?
