Evaluate \(\int\)(cos4x + sin3x)dx

A.

sin4x - cos3x + k

B.

sin4x + cos3x + k

C.

\(\frac{1}{4}\)sin4x - \(\frac{1}{3}\)cos3x + k

D.

\(\frac{1}{4}\)sin4x + \(\frac{1}{3}\)cos3x + k

Correct answer is C

\(\int (\cos 4x + \sin 3x) \mathrm d x\)

= \(\frac{1}{4} \sin 4x - \frac{1}{3} \cos 3x + k\)

A.

7

B.

3

C.

6

D.

5

Correct answer is D

P = 5x + 3, P = wx + 5
M1 = 5, M2 = w
M1 = M2 (parallel lines)
w = 5

From the diagram above, Find the value of < ROP

A.

110o

B.

70o

C.

95o

D.

85o

Correct answer is C

< ROP = 95o (Exterior angle of cyclic quadrilateral)

890.

In the diagram above, l1 is parallel to l2, Find the value of < PMT

A.

82o

B.

36o

C.

72o

D.

118o

Correct answer is A

< MPT = 180o - 118o = 62o

< PML = 62o ( Alternative angle)

y + 2y + 10o + 62o = 180o (Angles on a straight line)

3y = 180 - 72
\(\frac{3y}{3}\) = \(\frac{108}{3}\)
y = 36o

< PMT = 2y + 10 = 2(36) + 10 = 82o
