Find sin 2x, cos 2x, and tan 2x if cos x = sin 2x = cos 2x = tan 2x = 0 X 3 and x terminates in quadrant IV. 0/6 S 13 ?

Q: epresent 3 sin x + 6 cos x in a form A sin(x + p), use radians for p.

A:

Q: 4 cos 2x + 10 sin x – 7 = 0?

A:

Q: s 4

A: To simplify (cos 3x)(cos x)-(sin 3x)(sin x)

Q: Find sin 2x, cos 2x, and tan 2x if tan x= and x terminates in quadrant I. 3 sin 2x !! cos 2x tan 2x…

A:

Q: Show sin 3A = 3 sin A cos²A - sin A.

A: Explanation: Given that: sin3A=3sinAcos2A-sinA Concept: sin3A=3sinA-4sin3A sin2A+cos2A=1

Q: Show that sin 2x Þ 2 sin x by substituting 30 degree for x and then simplifying both sides.

A: To prove: sin2x≠2sinx For x=30°

Q: If sin 5x + 22 = cos 4x + 14 find x

A: Use the concept of  maximum minimum values od Sine and cosine functions.

Q: tan x= -4 and sin x is negative

A: Here tanx=-4we know trigonometric identity,sec2x=1+tan2xsec x=±1+tan2xsec x=±1+(-4)2sec…
