若函数f(x)=asin2x+btanx+1,且f(5)=—3,求f(π+5)?若函数f(x)=asin2x+btanx+1,且f(5)=—3,求f(π+5)?若函数f(x)=asin2x+btanx

若函数f(x)=asin2x+btanx+1,且f(5)=—3,求f(π+5)?
若函数f(x)=asin2x+btanx+1,且f(5)=—3,求f(π+5)?

若函数f(x)=asin2x+btanx+1,且f(5)=—3,求f(π+5)?
f(5)=asin2*5+btan5+1=-3
f(π+5)=asin(2(π+5))+btan(π+5)+1
=asin(10+2π)+btan(5+π)+1
=asin2*5 +btan5 +1
=-3
