Name the x-values for which the sine function and the cosine function equal to zero simultaneously in the domain 0°< x < 360° Name the x-values for which the tangent function is undefined in the domain 0°< x < 360°. Explain why the tangent function is undefined at those x-values.
A. GRAPHS OF THE TWO BASIC FUNCTIONS: SINE and COSINE y=sinx 1 ... Period - length of the smallest domain interval which corresponds to a complete ... amplitude = I a | = 3 The function has a maximum y value of 3. 2 2 ... denominator, cos x, equal to zero (to avoid division by zero). Thus, for ... 0 for these x values
@ikatouni ok i'm confused lol. what would our answer be?
Identify the domain and range of the six basic trigonometric functions. .... Just like sin(x), the x-values never "escape" from the unit circle, so they stay between −1 and 1. ... The name of the tangent function comes from the tangent line, which is a line .... First of all, at 0° itself, the cotangent is undefined because the segment is
I definitely agree with @ikatouni Good job
did u find what the segment is that ur answer
@ikatouni no i don't know how :( i'm not sure how to find the answer.
do u have any answer choices
@ikatouni no :( i wish i did lol
can u just tell me the answer for the two questions? please?
The graph repeats itself because the cotangent function is periodic
that's the answer
for both?
Through Quadrant I that height gets larger, starting at 0 .... itself, the cotangent is undefined because the segment is parallel to the ray the other one
oh thats the answer for the second one?
but it says name the x-values? what are the x-values?
Recall from Trigonometric Functions, that `tan x` is defined as: ... `0` in the denominator of the fraction and this means the fraction is undefined. ...
@nipunmalhotra93 do you know the answers?
I just gave it to u ^^
@veraewing There's no x for which both sinx and cosx are 0. One of the explanations for that could be that (sinx)^2+(cosx)^2=1 for all x. So both being 0 is not possible. tan=sin/cos. So, it'll be undefined at all those points where cos is 0. So the answer for part b is 90 and 270.
