Example 3 - Find integrals (i) sin x + cos x dx - Class 12


  1. Chapter 7 Class 12 Integrals (Term 2)
  2. Serial order wise


Example 3 Find the following integrals: (i) ∫▒(sin⁡x+cos⁡x ) dx ∫▒(sin⁡𝑥+cos⁡𝑥 ) 𝑑𝑥 =∫1▒(sin⁡𝑥 ) 𝑑𝑥+∫1▒〖〖(cos〗⁡𝑥) 〗 𝑑𝑥 =−𝐜𝐨𝐬⁡𝒙+𝐬𝐢𝐧⁡𝒙+𝑪 As ∫1▒(sin⁡𝑥 ) 𝑑𝑥=−cos⁡𝑥+𝐶 ∫1▒〖〖(cos〗⁡𝑥) 〗 𝑑𝑥=sin⁡𝑥+𝐶
