Tan^2x+sec^2x=1 for all values of x. <br> true or false?
amid [387]

This is not true.

\tan^2x+\sec^2x=\dfrac{\sin^2x}{\cos^2x}+\dfrac1{\cos^2x}=\dfrac{1-\cos^2x+1}{\cos^2x}=2\sec^2x-1

2\sec^2x-1=1\implies\sec^2x=1\implies\sec x=\pm1\implies x=n\pi

where is n is any integer. So suppose we pick some value of x other than these, say x=\dfrac\pi4. Then

\tan^2\dfrac\pi4+\sec^2\dfrac\pi4=1+2=3\neq1

Which statement is not true about the data shown?
Dmitrij [34]

Answer:

believe it is "the median is 82."

Step-by-step explanation:

55,66,82,89,90,92

there are 6 numbers so in order to find the median here you would have to add 82 and 89 together and then divide by 2.

82+89=171

171/2=85.5

hence "the median is 82." is the right answer
