WebStep 3: Compare both sides of the equals (comparing coefficients of sinθ and cosθ) Hence we can form two equations, Comparing sinθ: 4=Rcosα. Comparing cosθ: 3=Rsinα. Step 3: Finding R (by squaring both sides of our equations) 16=R 2 cos 2 α and 9=R 2 sin 2 α. By adding these equations together we can show: 25=R 2 cos 2 α+R 2 sin 2 α ...

WebNotice that Thus, cos θ = x/ r and sin θ = y/r cannot be greater than 1 or less than −1, depending on whether x and y are positive or negative (r = x when y = 0 and r = y when x = 0). So we conclude that the range of cos θ and sin θ is, {y − 1 ≤ y ≤ 1} .

So, if r = 3sinθ, multiply both sides by r to get r 2 = 3rsinθ.. Therefore, x 2 + y 2 = 3y. So, x 2 + y 2 - 3y = 0.. Completing the square on the y-terms, we have x 2 + (y 2 - 3y + 9/4) = 9/4. So, (x - 0) 2 + (y - 3/2) 2 = (3/2) 2.This is a circle with center (0, 3/2) and radius 3/2.

WebThe trigonometric R method is a method of rewriting a weighted sum of sines and cosines as a single instance of sine (or cosine). This allows for easier analysis in many cases, as a single instance of a basic trigonometric function is often easier to work with than multiple are. The R method is most often used to find the extrema (maximum and minimum) of …
