Answer:
The prove is below
Explanation:
From trigonometric identities:
[tex]cos2A=cos(A+A)=cos^2A-sin^2A\\sin2A=sin(A+A)=2sinAcosA\\sin4A=sin(2A+2A)=2sin2Acos2A=2(2sinAcosA)(cos^2A-sin^2A)=4sinAcos^3A-4cosAsin^3A\\secA=\frac{1}{cosA}[/tex]
Therefore:
[tex]\frac{1}{4}sin4AsecA = \frac{1}{4}( 4sinAcos^3A-4cosAsin^3A)\frac{1}{cosA}\\= sinAcos^3A-cosAsin^3A(\frac{1}{cosA} )\\=sinAcos^2-sin^3A\\=sinA(cos^2A-sin^2A)\\But\ cos^2A-sin^2A=cos2A\\Therefore:sinA(cos^2A-sin^2A)=sinAcos2A\\\frac{1}{4}sin^4Acos2A=sinAcos2A[/tex]

Stress. It's a part of life, no matter who you are, where
you live, or how old you are. Stress has a nasty reputation
for being something people should avoid at all cost
because of how-you guessed it-stressful it is. However,

harder or faster. Unfortunately, stress frequently ends up
being an unpleasant event for people.

Answer:
As we all know, when we are in a weakened position where we feel as if things are going from bad to worse, it can be very difficult to find our balance, or swim against the tide, or, recover and regain stability.

Some of the various benefits of becoming more resilient are listed below.
Improved learning and academic achievement.
Lower absences from work or study due to sickness.
Reduced use of risk-taking behaviours such as excessive drinking, smoking or use of drugs.
Increased involvement in community or family activities.
A lower rate of mortality and increased physical health.
