WebFor what values of t, 1 ≤ t ≤ 12, is the cost exactly $80? 58) The average daily temperature T of a city in the United States is approximated by . T = 55 - 23cos(2π/365)(t - 30) where t is in days, 1 ≤ t ≤ 365, and t = 1 corresponds to January 1. For what range of values of t is the average daily temperature above 70°F? WebMar 27, 2024 · As we know that cos θ is negative in 2 nd and 3 rd quadrant and ∵ 0 ≤ θ ≤ 2π. ⇒ θ = 2π/3, 4π/3. Hence, θ = 2π/3, 4π/3 are the solution of the given equation. Download Solution PDF.

WebThe solutions in 0 ≤ θ ≤ 360 are 60 degrees and 300 degrees but we can add 360 to each of these and 60 + 360 is in the same position as 60 so cos 420 = ½. Also 300 + 360 is in the same position as 300 so sin660 = ½. So the General solution in degrees is: WebFind, in degrees, the value of θ in the interval 0 . ≤θ < 360° for which . 2cos. 2 . θ − cosθ − 1 = sin. 2. θ. Give your answers to 1 decimal place where appropriate. (Total 8 marks) 21. (a) Sketch, for 0 ≤ x ≤ 360°, the graph of y = sin (x + 30°).
