Since the derivative of cos x is -sin x, therefore the graph of the derivative of cos x will be the graph of the negative of -sin x.Derivative of Cos x - FormulaNow, we will write the derivative of cos x mathematically. The derivative of a function is the slope of the tangent to...
The derivative of sec^2x is equal to 2 sec^2x tanx. It is mathematically written as d(sec^2x)/dx = 2 sec2x tanx.
Prove the derivative rules fory=cosxandy=cotx. Derivative Definition: If the left- and right-hand derivatives of a function at a particular point are equal, then the functiony=f(x)is said to be differentiable. The formula for the left-hand derivative is given asLHD=limh→0...
The derivative of "High over Low" is:"Low dHigh minus High dLow, over the line and square the Low"Example: What is the derivative of cos(x)/x ? In our case: f = cos g = x We know (from the table above): f' = −sin(x) g' = 1 So: the derivative of cos(x)x = ...

Quotient rule gives us a formula that we can use to derive fractions. If both the numerator and the denominator of {eq}\displaystyle \frac{f(x)}{g(x)} {/eq} are differentiable, then its derivative is given by the following formula. {eq}\displaystyle D_x\left( \frac{f(x)}{g(x)...
d dx sin x = cos x.We have established the formula.The derivative of cos xd dx cos x = −sin x To establish that, we will use the following identity:cos x = sin ( π2 − x). A function of any angle is equal to the cofunction of its complement. ...
Let,y= cosec x⇒ y = 1sinx⇒ y = (sinx)-1 Use the formula of the chain rule y = f(g(x))⇒dydx = f'(g(x))×g'(x) Now calculate the derivative: dydx=-(sin x)-2×ddx(sin x)⇒ dydx=-cos xsin x×1sin x⇒ dydx=-cot x . cosec x Hence, the derivative of ...
slope is (y1−y0)/(x1−x0). Another way to express this formula is [f(x0+h) −f(x0)]/h, ifhis used forx1−x0andf(x) fory. This change in notation is useful for advancing from the idea of the slope of a line to the more generalconceptof the derivative of a ...
