Answer to: Use the product-to-sum formulas to rewrite the product as a sum or difference. sin ( x + y ) cos ( x y ) By signing up, you'll get

Replace with in the formula for period. sin(x-y) = sinxcosy - sinycosx. The theroem of the broken chord leads us to the trig identityabove. So, we start by looking at the diagram that was createdon the previous page. To refresh our memory, the diagram is below. Recall the theorem of the broken chord states that AB + BF= FC. In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle.

Sin x y

If x and y are the angles of a right angle triangle, then x = y = 45 deg, and sin x = sin y = sin 45 = 0.707. If x and y are two different angles not connected to each other by any geometrical figure, then x and y can be any value from 0 to 90 deg. 2.4K views · View upvotes. 1.

% b) Betrakta följande begynnelsevärdesproblem för systemet av första ordningen. % x' = cos(x-y), x(0) = x_0. % y' = sin(xy), y(0) = y_0.
