derivative of 2 sin x + 3/cos x

Find Derivative of 2sin(x): We need to find the derivative of the function $ f(x) = 2 \sin(x) + \frac{3}{\cos(x)} $. We will use the sum rule for derivatives, which states that the derivative of a sum is the sum of the derivatives. We will also use the derivative rules for sine and cosine functions.Find Derivative of 3/cos(x): First, let's find the derivative of the first term, $ 2 \sin(x) $. The derivative of $ \sin(x) $ with respect to $ x $ is $ \cos(x) $, so the derivative of $ 2 \sin(x) $ is $ 2 \cos(x) $.Combine Derivatives for f(x): Now, let's find the derivative of the second term, $ \frac{3}{\cos(x)} $. This is the same as $ 3 \sec(x) $, where $ \sec(x) $ is $ \frac{1}{\cos(x)} $. The derivative of $ \sec(x) $ with respect to $ x $ is $ \sec(x) \tan(x) $, so the derivative of $ 3 \sec(x) $ is $ 3 \sec(x) \tan(x) $.Combining the derivatives of both terms, we get the derivative of the function $ f(x) $ as $ f'(x) = 2 \cos(x) + 3 \sec(x) \tan(x) $.

Q. derivative of

2 \sin x + \frac{3}{\cos x}

Find Derivative of $2$ sin(x): We need to find the derivative of the function $f(x) = 2 \sin(x) + \frac{3}{\cos(x)}$ . We will use the sum rule for derivatives, which states that the derivative of a sum is the sum of the derivatives. We will also use the derivative rules for sine and cosine functions.
Find Derivative of $3$ /cos(x): First, let's find the derivative of the first term, $2 \sin(x)$ . The derivative of $\sin(x)$ with respect to $x$ is $\cos(x)$ , so the derivative of $2 \sin(x)$ is $2 \cos(x)$ .
Combine Derivatives for f(x): Now, let's find the derivative of the second term, $\frac{3}{\cos(x)}$ . This is the same as $3 \sec(x)$ , where $\sec(x)$ is $\frac{1}{\cos(x)}$ . The derivative of $\sec(x)$ with respect to $x$ is $\sec(x) \tan(x)$ , so the derivative of $3 \sec(x)$ is $3 \sec(x) \tan(x)$ .
Combine Derivatives for f(x): Now, let's find the derivative of the second term, $\frac{3}{\cos(x)}$ . This is the same as $3 \sec(x)$ , where $\sec(x)$ is $\frac{1}{\cos(x)}$ . The derivative of $\sec(x)$ with respect to $x$ is $\sec(x) \tan(x)$ , so the derivative of $3 \sec(x)$ is $3 \sec(x) \tan(x)$ .Combining the derivatives of both terms, we get the derivative of the function $f(x)$ as $3 \sec(x)$ $0$ .
