Use the family of solutions in part (a) to find an explicit solution of the first- order initial-value problem y, 1 + y2, γ(0)-0. The correct answer is: A To solve the equation tan(x+y)tan(x−y)=1, we can use the identity for the tangent of a sum and difference. Nov 26, 2021 ... The general solution of the differential equation (d y/d x) =y tan x-y2 sec x is (A) tan x=(c+ sec x) y (B) sec y=(c+ tan y) x (C) sec x=(c+ ... May 10, 2024 ... This plot contains fine detail that has not been fully resolved warning disappears. Then pan around the graph, mentally assembling the complete picture. Let y = tan(x) Recall the definition of tan(x) as sin(x)/cos(x) Therefore y = sin(x)/cos(x) Use the quotient rule, which states that for y = f(x)/g(x), ... Since the graph of the function tan t a n does not have a maximum or minimum value, there can be no value for the amplitude.
