Mathematics

cscx = sinx tan x + cos x

Using xsx x = 1/sin x and tan x = sin x/cos x

\frac{1}{sin x} = sinx *\frac{sinx }{cos x} + cosx

\frac{1}{sin x} = \frac{sin^2x +cos^2x}{cos x}

\frac{1}{sin x} = \frac{1}{cos x}

Multiplying both sides by cos x

\frac{cos x}{sin x} = 1

cot x =1

Correct option is d .

Answer: d. cotx=1

Step-by-step explanation: cosecx=sinxtanx+cosx

                             ⇒             cosecx=  sinx×\frac{sinx}{cosx} +cosx

                             ⇒              cosecx=\frac{sin^{2}x  }{cosx} +cosx

                             ⇒          cosecx= \frac{sin^{2}x+cos^{2} x }{cosx}

                             ⇒            cosecx= 1/cosx     (since sin²x+cos²x=1)

                            ⇒             1/sinx=1/cosx

                           ⇒             cosx/sinx=1

                            ⇒             cotx=1

If f(x) = 6 – 5x and g(x) = 4x – 1, evaluate f(x) – g(x) for x = –2.
pogonyaev
Hello :
<span>f(x) = 6 – 5x and g(x) = 4x – 1
f(x)-g(x) = 6-5x-(4x-1) = 6-5x-4x+1 = -9x+7
whene x = - 2
f(x)-g(x) = -9(-2)+7 = 25......(answer : D)</span>
