(2) Tinh a) ∫_0^2 π( 2 x + cosx ) dx b) ∫_0^3| x - Dicamon

Question

(2) Tinh a)  ∫_0^2 π( 2 x + cosx ) dx b)  ∫_0^3| x - 2 | dx c)  ∫_1^2( 3^x - 3/x ) dx  a)  ∫_0^- 2| 2 x - 3 | dx e)  ∫_∴ = π/6^π/3( 1/cos^2x - 1/sin^2x ) dx

Answer

c)  . [ tanx + x|_( π / 6  )^π / 3 ] , [ = tan( π/3 ) + ( π/3 ) - tan( π/6 ) - ( π/6 ) ] , [ = 0  ]  . .

Giải giúp mình câu c câu d với ạ
