English: And then sin αx remains as it is and we are putting these limit 0 to ∞ plus again the integration of this e^(−x), so that minus and this minus will make it plus here, then we have this α which is coming because of the sin αx was differentiated here, so we have the cosαx with this α term.
Kannada: ತದನಂತರ, sin αx ಹಾಗೆಯೇ ಉಳಿದಿದೆ ಮತ್ತು ನಾವು 0 ರಿಂದ ∞ ಎಂಬ ಮಿತಿಯನ್ನು ಜೊತೆಗೆ ಈ e^(−x) ನ ಅನುಕಲನವನ್ನು ಹಾಕುತ್ತಿದ್ದೇವೆ.
