Derivative of sin(x+y)

Mathematics
1 answer:
vlabodo [156]3 years ago
4 0

Answer:

\frac{dy}{dx}  =  \frac{ \cos(x + y)}{[1 - \cos(x + y)] }

Step-by-step explanation:

Let y = sin(x+y)

Differentiating with respect to x on both sides.

\frac{dy}{dx}  =  \frac{d}{dx}  \sin(x + y) \\  \\  \frac{dy}{dx}  =  \cos(x + y)\frac{d}{dx}  (x + y) \\  \\ \frac{dy}{dx}  =  \cos(x + y)(1 + \frac{dy}{dx}) \\  \\  \frac{dy}{dx}  =  \cos(x + y) +\cos(x + y) \frac{dy}{dx} \\  \\  \frac{dy}{dx}   - \cos(x + y) \frac{dy}{dx} =  \cos(x + y) \\  \\  \frac{dy}{dx}  [1 - \cos(x + y)] =  \cos(x + y) \\  \\ \purple {\bold {\frac{dy}{dx}  =  \frac{ \cos(x + y)}{[1 - \cos(x + y)] }}}

Select the correct inequality for the graph given
Kaylis [27]

Answer:

y<= 3x-1

Step-by-step explanation:

When it comes about inequalities, keep in mind the following

the < sign means that the regions is under whatever is to other side, and the > means that the region is above whatever is on the other side of the sign

So, we see for the graphic that there is a region below a line, this suggests us that there is a < sign implied

The other thing is that there is a convention in math, is the line is graphed using a dashed line, it meas that it is not part of the region, if the line is graphed using a solid line (a continued line) then the line is inside the region, hence there is a = sign implied.

So the answer is y<= 3x-1

Joshua finds the perimeter of the following composite figure composed of a square and right triangle so that a braid may be cut
Bumek [7]

The perimeter of a shape is the sum of its side lengths.

<em>Joshua miscalculated the third length of the triangle</em>

First, we calculate the third length (x) of the triangle.

Because the triangle is right-angled, we can make use of Pythagoras.

So we have:

x^2 = 7^2 + 7^2

x^2 = 2(7^2)

Take square roots of both sides

x = \sqrt{2(7^2)

x = 7\sqrt{2

The other shape in the figure is a square.

So, the perimeter (P) is

P = 7 + x + x + x + 7 ---- i.e. the sum of the visible lengths

So, we have:

P = 7 + 7\sqrt2 + 7\sqrt2 + 7\sqrt2+ 7

Evaluate like terms:

P = 14 + 21\sqrt2

Hence, Joshua's error is that:

<em>He miscalculated the third length of the triangle</em>
