​Menghitung integral tentu dengan menggunakan integral tak tentu

1.  Gunakan rumus :  

Multiple Choice

$$1.\ Hitunglah\ \int_0^2\ 100\ dx\ =....$$  

• 0

• 2

• 10

• 20

• 200

Jawaban no 1 : 200

pembahasan :

= ⌈100 x ⌉₀²

= 〈100 . 2〉-〈100 . 0〉

= 200-0

=200​

Multiple Choice

$$2.\ \int_0^124x\ dx=...$$  

• 0

• 1

• 2

• 12

• 24

​Jawaban no 2 : 12

= 24/2 x ²⌉¹₀

= 12 x²⌉​¹₀

= 12 .1² - 12. 0⁰

^{= 12 - 0}

^{= 12}​

$$3.\ \int_0^3\ \lceil3x^2+4x-5\rceil dx\ =....$$  

• 0

• 1

• 25

• 30

• 35

​Jawaban no 3 : 30

=(x³ + 2x² -5x)₀³

=(3³ + 2. 3² – 5.3)-(0)

=27+18-15

=30

Multiple Choice

$$4.\ \int_{-1}^1\left(5x\ +\ 3\right)\ dx\ =....$$  

• 0

• 1

• 3

• 6

• 12

Jawaban no 4 : 6

=5/2 x²+3x⌉¹_-1

=〈5/2 1² + 3.1〉​-〈5/2 -1² + 3.-1〉

=〈​5/2 + 3〉-〈5/2 -3〉

=11/2 - -1/2

=11/2 + 1/2

=12/2 = 6​
