Question

if 0 less than x less than π and cos x + sin x = ½ , then tan x =​

Answer 1

Step-by-step explanation:

: (4 - √7) / 3 B: -(4 + √7) / 3 C: (1 + √7) / 4 D: (1 - √7) / 4

tanx=−4±√73 Explanation: cos x + sin x = 1/2 Divide both sides by cos x 1+tanx=12cosx=secx2 Square both sides (1+tanx)2=sec24 4(1+tan2x+2tanx)=sec2x ... More
