According to given sum,
sin (1+tan)+cos (1+cot)=sec+cosec
=> LHS= sin (1+tan)+cos (1+1/tan)
=> sin (1+tan)+cos (1+tan)/tan
=> (1+tan)(sin+cos/tan)
=> (1+tan)(sin.tan+cos)/tan
=> (1+tan)(sin2/cos+cos)/tan
=> (1+tan)(sin2+cos2)/tan.cos
=>(1+tan)/tan.cos
=>(1/tan.cos)+tan/tan.cos
=>( cot/cos)+(1/cos)
=> cosec +sec
LHS= RHS.
