Integration of tanx
Integration of tanx
Tanx represents the tangent function of x, where x is the variable. Integration of tanx involves finding the antiderivative of tanx. The antiderivative is a function whose derivative is equal to the original function.
Basic integral of tanx
The integral of tanx can be represented as ∫tanx dx.
Using trigonometric identities
To integrate tanx, we can use trigonometric identities to rewrite the expression in a more manageable form. One useful identity is:
tan^2x = sec^2x - 1
Using this identity, we can rewrite the integral of tanx as:
∫tanx dx = ∫(sec^2x - 1) dx
Integration of sec^2x
The integral of sec^2x is well-known and can be easily evaluated. The integral of sec^2x dx is equal to tanx + C, where C is the constant of integration.
Therefore, the integral of tanx can be rewritten as:
∫tanx dx = ∫(sec^2x - 1) dx = ∫sec^2x dx - ∫1 dx = tanx - x + C
Conclusion
In conclusion, the integration of tanx can be determined by using trigonometric identities to rewrite the expression in a more manageable form. By applying the identity that relates tanx to sec^2x, we can simplify the integral and evaluate it. The final result is tanx - x + C, where C represents the constant of integration.
