Differentiate... How to solve this type of problem? y = cos^2(x^2 + x^3)

Licemer1 [7]

Answer:

$\frac{d y}{d x} = - (2 x + 3 x^{2} )sin2(x^{2} +x^{3})$

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given y = cos² (x² + x³) ....(i)

By using differentiation formulas

a) $\frac{d}{dx} (cosx) = -sinx$

b) $\frac{d}{dx} (x^{n} ) = n x ^{n-1}$

<u><em>Step(ii):-</em></u>

Differentiating equation (i) with respective to 'x'

<em>First apply formula </em> $\frac{d}{dx} (x^{n} ) = n x ^{n-1}$ <em></em>

$\frac{d y}{d x} = 2 cos (x^{2} +x^{3} )^{2-1} \frac{d}{d x} (cos(x^{2} +x^{3})$

<em>Now we will apply formula </em>

$\frac{d}{dx} (cosx) = -sinx$

$\frac{d y}{d x} = 2 cos (x^{2} +x^{3} ) (-sin(x^{2} +x^{3})\frac{d}{dx} (x^{2} +x^{3} )$

<em>Again apply formula </em> $\frac{d}{dx} (x^{n} ) = n x ^{n-1}$ <em></em>

$\frac{d y}{d x} = 2 cos (x^{2} +x^{3} ) (-sin(x^{2} +x^{3}) (2 x + 3 x^{2} )$

$\frac{d y}{d x} = -2 sin (x^{2} +x^{3} ) cos(x^{2} +x^{3}) (2 x + 3 x^{2} )$

we know that trigonometric formulas

Sin 2θ = 2 sinθ cosθ

$\frac{d y}{d x} = -sin2(x^{2} +x^{3}) (2 x + 3 x^{2} )$

<u><em>Final answer:-</em></u>

$\frac{d y}{d x} = - (2 x + 3 x^{2} )sin2(x^{2} +x^{3})$

Write a equation for 10 less than j is 35

kakasveta [241]

Answer:

$j - 10 = 35$

Step-by-step explanation:

Given: 10 less than $j$ is 35.

To find: The equation of the given situation.

Solution: We need to write an equation for 10 less than $j$ is 35.

Here, we will break down the sentence to form the equation.

10 less than $j$ means $j - 10$ .

Then, it says 10 less than $j$ is 35 which means it is equal to 35.

So, the sentence 10 less than $j$ is 35 can be written as 10 less than $j$ is equal to 35.

Now, 10 less than $j$ is equal to 35 can be shown as $j - 10 = 35$ .

Therefore, the required equation is $j - 10 = 35$ .
