Answer:

yes,.to obtain sinx as 1 the angle must be 90degrees

so the answer is correct

but there are more solutions like when the cosine angle is 45 the answer is 1

and when x is 450 still sinx = 1..that is to say sin450= 1

2x^2(x+2) +6(x+2) = (2x^2 +6)(x+2) = 2(x^2 +3)(x+2)

so this mean that the 4th choice will be right sure

Decide whether the equations is a trigonometric function identity, EXPLAIN.

hodyreva [135]

(1) Answer: Identity true

$\cos^2x(1+\tan^2x)=\cos^2x(1+\frac{sin^2x}{cos^2x})=\\= \cos^2x\frac{cos^2x+sin^2x}{cos^2x}=1$

(2) Answer: Identity true

$\sec x \tan x(1-\sin^2x)=\sin x\\\frac{1}{\cos x}\frac{\sin x}{\cos x}(\cos^2x)=\sin x\\\sin x = \sin x$

(3) Answer: Identity true

$\sin^2(\theta)\csc^2(\theta)=\sin^2(\theta)+\cos^2(\theta)\\\sin^2(\theta)\frac{1}{\sin^2(\theta)}=\sin^2(\theta)+\cos^2(\theta)\\1 = 1$

Answer:

2n + 2

Step-by-step explanation:

The formula for nth term of an arithmetic progression is $an = d*n+a1-d$

In this example we have d = 2 (difference, +2 each time) and a1 =4 (first term of sequence).

$an=d*n+a1-d\\an=2n+4-2\\an=2n+2$
