cos(x). Cross multiplying, we get: tan(x) x cos(x) = sin(x). Divide each side of the equation by tan(x): y= sin(x), y= cos(x), y= tan(x) tables Answer to Find sin(x), cos(x) and tan(x) Round your answer to the nearest hundredth. sin(x) = cos(x) = tan(x) = 2 Jan 2008 There will be no changes to other Yahoo properties or services, or your Yahoo account. You can find more information about the Yahoo Answers Problem. A geometric sequence $(a_n)$ has $a_1=\sin x$ , $a_2=\cos x$ , and $ a_3= \tan x$ for some real number $x$ . For what value of $n$ in radians, for each expression.

From equation (3) we rearrange so that. adj = hyp * cos x. Substitute these values into equation (1) tan x = (hyp * sin x) / (hyp * cos x) Cancel out the common hyp term, and you have. tan x = sin x / cos x 分母不能等于0，当cosx=0时，tanx不存在。所以tanx=sinx/cosx 后面要加限制条件 x≠π/2+2kπ 2016-03-26 · sin(x)tan(x)+cos(x)=sec(x) sin(x)tan(x)+cos(x) = sin(x)sin(x)/cos(x)+cos(x) =sin^2(x)/cos(x)+cos(x) =sin^2(x)/cos(x)+cos^2(x)/cos(x) =(sin^2(x)+cos^2(x))/cos(x) =1 2018-03-26 · How do you simplify #cos x + sin x tan x#?

Review this resource. Periodicity: sinx, cosx have period 2π; tanx, cotx have period π. Symmetry: cos is an even function, sin, tan, cot are odd.

check-circle. Answer. Step by step solution by experts to help you in doubt Let sinx+cosx=√2sin(x+π4)=a, then a can take any value between −√2 and √ 2. We have sinxcosx=a2−12.
