Answer:
Step-by-step explanation:
sin(2x) = 2 sin(x) cos(x) cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. Now I am not sure if this is right but I remember another similar formula. Here is the correct formula cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
cos² x + sin² x = 1
I think it is 4%?
If not forgive me.
I’m Not 100% Sure, But I Would Think 13.1% Is The Answer.
Answer:
The provided statement is TRUE.
Step-by-step explanation:
The function <em>f</em> is an expression in variable <em>x</em>.
The entire expression can either be denoted by f (x) or <em>y</em>.
For instance consider the quadratic expression:
f (x) = ax² + bx + c
≡ y = ax² + bx + c
So, on computing the value of f (2), it implies that we are computing the value of y for <em>x</em> = 2.
Thus, the provided statement is TRUE.
