8 июл. 2022 г. · Express sec−1(x) in terms of cos−1(x) ... I'm trying to algebraically solve for x in sec(x)=±2√33 . My first step was to isolate x by making the ... |
7 авг. 2014 г. · I know that cosecant is the inverse of sine, and secant is the inverse of cosine. However, that does not equal the right hand side of the equation. |
9 сент. 2015 г. · csc(x)=1sin(x). cot(x)=cos(x)sin(x). sec(x)=1cos(x). csc(x)cot(x)sec(x)=1sin(x) cos(x)sin(x)1cos(x)=cos2(x)sin2(x). =cot2(x). |
8 окт. 2014 г. · Try to write sec in terms of cos then simplify things and see how far you can get. Same thing as (3), write cot in terms of cos ... |
28 мар. 2018 г. · Secant of x = (1 / COsine of x) · COsecant of x = (1 /Sine of x) · COtangent of x = (1 / Tangent of x). |

5 июн. 2017 г. · Trying to write cscx in terms of cosx. Please tell me what I am doing wrong: Step 1 ... cosθ+secθ)2≥9 · 1 · Simplifying (cotθ+1)(cotθ+1)−csc2 ... |
4 апр. 2018 г. · Let sec−1(x)=y. Then sec(y)=x. Which means cos(y)=1x. So y=cos−1(1x). Therefore sec−1(x)=cos−1(1x). |
5 апр. 2015 г. · Naturally you want everything to be in terms of cosx and sinx, since they have simple identities. ... So: secx=1cosx and tanx=sinxcosx. |
15 мая 2013 г. · As far as I know arccos(x) is the inverse cosine function (cos(x)−1) and sec(x) = 1cos(x) (source Wolfram|Alpha). So why aren't they equal? |
