Given that y = x^2 +2x + 3, find dy/dx.

We use a typical rule for polynomials in the form y = axb , where a and b are real numbers. Also, for a polynomial equation y = axb +cx

How to differentiate e^x . sin(x)

ex sin(x) is a product of two functions: ex and sin(x). This means we can use the product rule.
Let ex = u and sin(x) = v
The differential of uv is u'v + v'u whe...

differentiate with respect to x : y = x^2 -5x

to find dy/dx, multiply each item by the power of the x, and then decrease the power of the x by 1.Step 1 : 2x^2 -15x (multiplying by power of x)Step 2 : 2x^1 -15x^0Therefore:dy/dx = 2x ...

Use implicit differentiation to find dy/dx of the equation 3y^2 + 2^x + 9xy = sin(y).

Differentiating each term separately, and using implicit differentiation to differentiate the functions of y by differentiating with respect to y and multiplying by dy/dx, we can obtain 6ydy/dx + ln2<...

Differentiante y = arctan(c)

y = arctan(x)tan(y) = xsec2(y) = dx/dyfrom cos2A + sin2A = 1, we know that 1 + tan2A = sec2A (divide by cos2A), so we substitute in1 + tan...
