Webx = 4cos(t) and y = 4sin(t) + 1 Given we require the object to start at (4,1), we can see that x(0) = 4 and y(0) = 1. Furthermore, x(t) and y(t) have periods of 2pi as required. The last trick to note is that we require the object to travel clockwise, so we need to invert t. Therefore, x(t) = 4cos(-t) and y(t) = 4sin(-t) +1: t ∈ [0, 2pi] WebFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. bird allergy skin rash treatmentWebMar 28, 2024 · A signal x (t) is a said to be periodic with a period T if x (t ± T) = x (t) The time period for a signal in the form of A cos (ωt + ϕ) & A sin (ωt + ϕ) is T = 2 π ω.
