The only two situations where this … WebThe Minus Case. Similarly, for the minus case, we equate a sin θ − b cos θ with the expansion of R sin (θ − α) as follows (note the minus signs carefully): . a sin θ − b cos θ ≡ …

Finding the tangent line to the polar curve - Krista King Math

WebFeb 13, 2016 · rcos ( θ - π/6) = r cosθ cos ( π/6) - r sinθ sin (π/6) , Substitute rsin (θ and rcosθ from above and sin (π/6) = 1/2 ,cos (π/6) =√3 /2. r cos ( θ - π/6)= x√3 /2 + y (1/2), set this equal to the right hand side. x√3 /2 + y (1/2) = 2. x√3 + y = 4. y = - x√3 + 4.

Find the slope of the tangent line to the given polar curve - Quizlet

WebGraph r 1 = 3 cos θ, r 2 = sin θ. (i) At which angle θ does the 2 curves intersect? a. 3 5 π b. 3 π c. 0 d. 6 11 π e. 6 7 π . (ii) Which choice below represents the area of the region that lies inside the first curve and outside the second curve in the first quadrant? a. 2 1 ∫ π /6 π /2 r 1 2 d θ − 2 1 ∫ 0 π /6 r 2 2 d θ b. WebWe know that the maximum value of a cos θ + b sin θ + c is c + ( a 2 + b 2). Substituting a = 13 2, b = - 3 √ 3 2 and c = 3, we get, The maximum value = 3 + 169 4 + 27 4 = 3 + 7 = 10.
